How To Choose The Right Rectifier & Capacitor For Rectifing AC to DC
 
10:50
(Please read calculation examples below) In this video I discuss how to choose the right size & spec'd full bridge rectifier & electrolytic capacitor. In the interests of avoiding confusing calculations please carefully study the below examples. Note in "Example 2" how the results = 200 this could easily be mistaken for 200uf. However, it is infact 200,000uf Example 1: 10 amps x 8.3ms / 5.5volts = 15.0909 (15,0909uf) Example 2: 10amps x 10ms /0.5volts = 200 (200,000uf) - Schematix -

Panasonic Hybrid Capacitors Provide a Low ESR with a Higher Withstanding Voltage
 
02:06
http://www.futureelectronics.com/en/Search.aspx?dsNav=Ny:True,Ro:0,Nea:True,N:454-4294938236 Typical Polymer Capacitors have an excellent equivalent series resistance or ESR. However, due to the nature of the Polymer raw material the voltage rating of this style of capacitor can only go as high as 80V DC. In comparison, a conventional electrolytic capacitors can handle higher voltages and has a larger charge capacity. However, the ESR characteristics are inferior to a Polymer Capacitor. Hybrid Capacitors utilize a combination of liquid aluminum electrolyte and polymer as a dielectric material, providing a best of both worlds approach and creating a superior capacitor. The polymer contributes to a low ESR while the liquid aluminum electrolyte allows for a higher capacitance, higher withstanding voltage and a longer lifetime. Hybrid capacitors provide a tighter control over DC leakage current as compared to electrolytic capacitors. Also, a hybrid capacitor opens upon failure where a polymer capacitor short circuits on failure. Due to its enhanced ESR and ripple current handling capabilities hybrid capacitors are useful in applications that require high frequency switching at higher voltages. One hybrid capacitor can be used to replace multiple conventional surface mount electrolytic capacitors, thus saving space on your circuit board. http://www.futureelectronics.com/en/Search.aspx?dsNav=Ny:True,Ro:0,Nea:True,N:436-4294938236 Hybrid capacitors have excellent temperature characteristics and a high mean time to failure, making them especially useful in industrial applications where durability is paramount. Typical applications include automotive ECUs, motor drives, security cameras and LED lighting. For more information on Panasonic’s hybrid capacitors visit their website.

SIEMENS VFD G120P WITH BOP-2  PROGRAMMING & TESTING
 
04:37
A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter. Frequency (or hertz) is directly related to the motor’s speed (RPMs). In other words, the faster the frequency, the faster the RPMs go. If an application does not require an electric motor to run at full speed, the VFD can be used to ramp down the frequency and voltage to meet the requirements of the electric motor’s load. As the application’s motor speed requirements change, the VFD can simply turn up or down the motor speed to meet the speed requirement. The first stage of a Variable Frequency AC Drive, or VFD, is the Converter. The converter is comprised of six diodes, which are similar to check valves used in plumbing systems. They allow current to flow in only one direction; the direction shown by the arrow in the diode symbol. For example, whenever A-phase voltage (voltage is similar to pressure in plumbing systems) is more positive than B or C phase voltages, then that diode will open and allow current to flow. When B-phase becomes more positive than A-phase, then the B-phase diode will open and the A-phase diode will close. The same is true for the 3 diodes on the negative side of the bus. Thus, we get six current “pulses” as each diode opens and closes. This is called a “six-pulse VFD”, which is the standard configuration for current Variable Frequency Drives.Let us assume that the drive is operating on a 480V power system. The 480V rating is “rms” or root-mean-squared. The peaks on a 480V system are 679V. As you can see, the VFD dc bus has a dc voltage with an AC ripple. The voltage runs between approximately 580V and 680V.We can get rid of the AC ripple on the DC bus by adding a capacitor. A capacitor operates in a similar fashion to a reservoir or accumulator in a plumbing system. This capacitor absorbs the ac ripple and delivers a smooth dc voltage. The AC ripple on the DC bus is typically less than 3 Volts. Thus, the voltage on the DC bus becomes “approximately” 650VDC. The actual voltage will depend on the voltage level of the AC line feeding the drive, the level of voltage unbalance on the power system, the motor load, the impedance of the power system, and any reactors or harmonic filters on the drive. The diode bridge converter that converts AC-to-DC, is sometimes just referred to as a converter. The converter that converts the dc back to ac is also a converter, but to distinguish it from the diode converter, it is usually referred to as an “inverter”. It has become common in the industry to refer to any DC-to-AC converter as an inverter.When we close one of the top switches in the inverter, that phase of the motor is connected to the positive dc bus and the voltage on that phase becomes positive. When we close one of the bottom switches in the converter, that phase is connected to the negative dc bus and becomes negative. Thus, we can make any phase on the motor become positive or negative at will and can thus generate any frequency that we want. So, we can make any phase be positive, negative, or zero.

EEVblog #626 - Ceramic Capacitor Voltage Dependency
 
27:58
Dave explains, shows, and measures a potentially big trap with using high value ceramic capacitors. Is your 10uF capacitor really 10uF in your circuit? You might be shocked!

DC Voltage Measurement using Oscilloscope
 
08:16
When DMM (Digital Multi-Meter) or voltmeter is not available, the oscilloscope can be used for measuring DC voltage. Even after calibration and warm-up of the device, there may be a DC offset. Instead of using the builtin measurements, the cursor may be more accurate for measurement. Note for limits of the device which may cause damage of the oscilloscope and injury, so work within the specs of the device.

Three phase three level flying capacitor inverter
 
03:01
Paper title: Dc-link current and voltage harmonics in three-phase three-level flying capacitor inverters with sinusoidal carrier based PWM authors names: Manel Hammami, Marija Vujacic, Gabriele Grandi affiliation: Dept. of Electrical, Electronic and Information Engineering Alma Mater Studiorum – University of Bologna, Italy Paper abstract: This paper concerns with the analysis and calcula­tion of the low-frequency dc-link input current and voltage ripple har­monic components in three-phase three-level flying capacitor in­verter topologies. As a first simplified approach, reference is made to si­nusoidal carrier-based PWM, and sinusoidal load cur­rents with unity power factor, well representing most of the grid-connected applications. The proposed method can be straight­forwardly ex­tended to centered PWM with any output power fac­tor angle. Based on the ripple requirements of dc-link voltage, an original simple and effective equation for designing the dc-link capacitor has been proposed, since design guidelines only for the flying ca­pacitors are reported in literature. Numerical simula­tions have been carried out by Matlab/Simulink in order to verify the pro­posed developments.

Adjustable DC-DC Step Up Boost Converter Power Supply Module testing and review
 
07:45
in this video i will show you Adjustable DC-DC Step Up Boost Converter Power Supply Module testing and review This module features the XL6009E1 4 Amp step up (boost) converter, which can take input voltages as low as 5V and step up the output to as high as 35V. This module has a multi-turn trimpot (potentiometer) that you can use to adjust the output voltage. Since the trimpot has 25 turns of adjustment you can easily adjust the output of the module to exactly the voltage you need. Boost converters are a great way to easily increase a given voltage, but that boost comes at the cost of less output current compared to input current. Since this is a boost converter the output voltage has to be higher than the supplied input voltage. If you need to decrease (step-down) a voltage consider using a buck converter such as our LM2596 buck converter module. We also offer a 2A boost converter if you don't need the full 4A

This is the full link to one of the videos by Rick McWhorter http://www.youtube.com/watch?v=IWxeWnnU4i0 (AllAmericanFiveRadio) Do download his book, it's free but the information is priceless! Rick has put a huge amount of effort and a lifetimes worth of experiences into his videos, I think you find them interesting and entertaining, but be warned, you'll get hooked! I have. In my videos, inevitably there will be things that I forget to mention and maybe some things I get wrong, please feel free to comment and put me right if I go wrong. It's some 40 odd years since I was involved with domestic radios, that was before I qualified as an electrician and subsequently moved on into high power high frequency electronic engineering. I'm not setting out to tell you how to repair radios, the fact that you've read this far probably means you're Interested in radio and I'm merely helping to confirm what you already know. With regards to safety, when I was training they told me that if 30 milliamps passes through you for 30 milliseconds can kill you. Don't make the mistake that thinking that an isolation transformer will protect you from being electrocuted. An isolation transformer, correctly installed, will only protect you from passing current from the mains electrical supply to earth, that's all. If you get across the HT AC or the HT DC that is the High Tension Alternating Current or High Tension Direct Current supply of the radio and the conditions are right, it will stop your heart and if there's no one around to start it again it might just stay stopped! Do use an isolation transformer but back that up with good safe working practice. I'm not setting out to teach you good working practice but do be aware volt for volt DC is more likely to stop your heart than AC but I can also tell you that both hurt and both can kill!

How to make 5 volt power supply in 5 minutes Easily
 
06:01
In this video, I have designed a simple 5 volt 1 amp DC power supply from AC mains (230V/120V AC) using an LM7805 voltage regulator. After watching this video you can easily make the 5 v power supply within 5 minutes. You can use this 5-volt regulator to supply your Arduino circuit or any 5v USB gadgets. This 5 volt supply can also be used as the mobile charger. In this project, I have not used Heat Sink with LM7805 but I will suggest you use a heat sink with 7805 ic. The whole process of making this 5 v supply is shown in steps so you can easily design this 5v regulator. The required components are: 1. LM7805 regulator 2. 0.1uF Capacitors (2nos) 3. 470uF Capacitor (1 no) 4. Diode 1N4007 (4nos) 5. Step Down Transformer [230/120V - 9V] 6. Connector 7. Connecting wires 8. Zero PCB Working Principle of this 5 v DC source: First, we are using a step-down transformer [Secondary rating 9V and 1 amp] to step down 230V/ 120V AC supply to 9 Volt AC. Then we rectify the 9V AC to 9 V DC using a diode bridge rectifier [Full wave rectifier]. After the rectifier, we have used Capacitors to filter the ripple from the circuit and fed it to the input of LM7805 voltage regulator. LM7805 regulate the 9 volt DC to 5 Volt DC and at the output of 7805 ic, we get constant 5 Volt DC output.

To download the project files referred to in this video visit: http://www.keysight.com/find/eesof-how-to-capacitors. For more information about Picotest visit: https://www.picotest.com Power supply switching ripple and control loop phase margin are dominated by the output inductor and the bulk capacitors. Simple RLC capacitor and inductor models can result in a design with more capacitors than necessary adding to the design cost, consuming valuable circuit board real estate and degrading the control loop performance. Most capacitor datasheets provide very limited information, such as maximum ESR at 100kHz and not the desired information regarding typical values and frequency dependancies of the C, ESR, and ESL. This short video will show how to make these measurements efficiently and how to use the results directly or create high fidelity measurement based models for simulation in ADS.

Esr Meter MESR100 v2 Hands on look at a low priced Equivalent series resistance meter.

For the price as an entry level esr meter i would recommend it the test leeds a bit short for in circuit testing But its a great little meter. Features: JINGYAN MESR-100 V2 Auto-ranging capacitor ESR and Low Ohm Meter Measuring range from 0.001 to 100.0R, support IN CIRCUIT Testing. Using true 100 KHz sine wave to measure the ESR value, which is equal to the testing method of capacitor manufacturer. What is ESR of capacitor? There is a series resistor inside a capacitor, by using 100kHz to remove the impedance 1/(2*pi*F*C), the impedance will become small, and we can then measure the true series resistor value. A bad E-capacitor will have a larger ESR and create a large ripple rather than filtering noise. Normally, a bad capacitor is larger than 3 ohm. Using this theory, we can measure to see if the capacitor is bad/ damaged or in good condition. Because this ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result it can be use as an in circuit tester as the low testing voltage will not turn on the semiconductor inside a circuit under test. Specification: 1) Accuracy: Up to 1% Wide Measurement Range: 1uF (for 0.1uF the error will be larger on equation 1/(2*pi*F*C) @ 100Khz ) 2) High Resolution: 4 digit, or 0.001Ohm @ 1 Ohm range 3) Measuring voltage: 40mV RMS (TESTING VOLTAGE) 4) Clamping voltage: 0.15V (open voltage) 5) Battery 2X AA 1.5V battery 6) External Power: 5V micro USB 7) Operating current 0.02A 8) Battery Life time: 80 Hours Thanks for watching, If you liked my videos and would like to support this channel you can make a donation @ http://goo.gl/GqtT4 or click the Show Your Support link, on are channel page and if you use bitcoins you can send us some bitcoins to 1MFGvF7NPaXC7RU5Trwo8z1dUbuowcuw5D Thanks for you support.

What is ELECTROLYTIC CAPACITOR? What does ELECTROLYTIC CAPACITOR mean?
 
02:36
What is ELECTROLYTIC CAPACITOR? What does ELECTROLYTIC CAPACITOR mean? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Electrolytic capacitor is the generic term for three different capacitor family members: 1. Aluminum electrolytic capacitors, 2. Tantalum electrolytic capacitors and 3. Niobium electrolytic capacitors All electrolytic capacitors (e-caps) are polarized capacitors whose anode (+) is made of a particular metal on which an insulating oxide layer forms by anodization, acting as the dielectric of the electrolytic capacitor. A non-solid or solid electrolyte which covers the surface of the oxide layer in principle serves as the second electrode (cathode) (-) of the capacitor. Due to their very thin dielectric oxide layer and enlarged anode surface, electrolytic capacitors have—based on the volume—a much higher capacitance-voltage (CV) product compared to ceramic capacitors or film capacitors, but a much smaller CV value than electrochemical supercapacitors. The large capacitance of electrolytic capacitors makes them particularly suitable for passing or bypassing low-frequency signals up to some mega-hertz and for storing large amounts of energy. They are widely used for decoupling or noise filtering in power supplies and DC link circuits for variable-frequency drives, for coupling signals between amplifier stages, and storing energy as in a flashlamp. Standard electrolytic capacitors are polarized components due to their asymmetrical construction, and may only be operated with a higher voltage (ie, more positive) on the anode than on the cathode at all times. Voltages with reverse polarity, or voltage or ripple current higher than specified (as little as 1 or 1.5 volts may suffice), can destroy the dielectric and thus the capacitor. The destruction of electrolytic capacitors can have catastrophic consequences (explosion, fire). Bipolar electrolytic (aka non-polarized) capacitors which may be operated with either polarity are special constructions with two anodes connected in reverse polarity.

This video demonstrates how the Ratio function can be combined with TSP scripting to turn the DMM7510, DMM6500, or DAQ6510 into a simple power meter. This is achieved by using a shunt resistor between the instrument’s Sense terminals which allows for the measuring of current. TSP scripting is then used to compute the voltage and current and therefore power being consumed by your device under test. A link to the scripting code is in the comments below.

DIY Homemade 30watt LED BULB with Transformerless power supply |easy and low cost

DIY Homemade 30watt LED BULB with Transformerless power supply |easy and low cost is very simple to design circuit we need some calculations for ppc capacitor please check below video u can better understand https://youtu.be/y9lbqQiWvk8 some household bulbs like LED bulb in these transformer power supply is use you can also create your own led bulb in easy way ** please like and subscribe** ************All Videos imp files are shared by link these link is only open 5hr so please subscribe and on the notification so u can download files *************** **circuit diagram link is given below** https://drive.google.com/open?id=18Jh... how to use specific capacitor for these power supply you can check below calculation for better understanding X Rated capacitor 400 Volt 225k 400v capacitor The X rated capacitor is designed for 250, 400, 600 VAC. Higher voltage versions are also available. The Effective Impedance (Z), Rectance (X) and the mains frequency (50 – 60 Hz) are the important parameters to be considered while selecting the capacitor. The reactance (X) of the capacitor (C) in the mains frequency (f) can be calculated using the formula: X = 1 / (2 ¶ fC ) For example the reactance of a 0.33µF capacitor running in the mains frequency 50Hz will be: X = 1 / {2 ¶ x 50 x 0.33 x( 1 / 1,000,000) } =9645.75 Ohms 0r 96.6 Kilo ohms. Rectance of the capacitor 0.33 uF is calculated as X = 1/2Pi*f*C Where f is the 50 Hz frequency of mains and C is the value of capacitor in Farads. That is 1 microfarad is 1/1,000,000 farads. Hence 0.33 microfarad is 0.33 x 1/1,000,000 farads. Therefore the rectance of the capacitor appears as 9645.75 Ohms 0r 96.6 Kilo ohms..To get current I divide mains Volt by the rectance in kilo ohm.That is 230 / 96.6 = 23.80 mA. Effective impedance (Z) of the capacitor is determined by taking the load resistance (R) as an important parameter. Impedance can be calculated using the formula: Z = √ R + X Suppose the current in the circuit is I and Mains voltage is V then the equation appears like: I = V / X The final equation thus becomes: I = 230 V / 96.6 = 23.80 mA. Therefore if a 0.33 uF capacitor rated for 230 V is used, it can deliver around 23 mA current to the circuit. But this is not sufficient for many circuits. Therefore it is recommended to use a 470 nF capacitor rated for 400 V for such circuits to give required current. X Rated AC capacitors – 250V, 400V, 680V AC x rated ac capacitors Table showing the X rated capacitor types and the output voltage and current without load capacitor and current Rectification Diodes used for rectification should have sufficient Peak inverse voltage (PIV). The peak inverse voltage is the maximum voltage a diode can withstand when it is reverse biased. 1N4001 diode can withstand up to 50 Volts and 1N4007 has a toleration of 1000 Volts. The important characteristics of general purpose rectifier diodes are given in the table. DC Smoothing A Smoothing Capacitor is used to generate ripple free DC. Smoothing capacitor is also called Filter capacitor and its function is to convert half wave / full wave output of the rectifier into smooth DC The capacitance value determines the amount of ripples that appear in the DC output when the load takes current. Voltage Regulation Zener diode is used to generate a regulated DC output. A Zener diode is designed to operate in the reverse breakdown region. If a silicon diode is reverse biased, a point reached where its reverse current suddenly increases. The value of R can be calculated using the formula: R = Vin – Vz / Iz Where Vin is the input voltage, Vz output voltage and Iz current through the Zener In most circuits, Iz is kept as low as 5mA. If the supply voltage is 18V, the voltage that is to be dropped across R to get 12V output is 6volts. If the maximum Zener current allowed is 100 mA, then R will pass the maximum desired output current plus 5 mA . So the value of R appears as: R = 18 – 12 / 105 mA = 6 / 105 x 1000 = 57 ohms Power rating of the Zener is also an important factor to be considered while selecting the Zener diode. According to the formula P = IV. P is the power in watts, I current in Amps and V, the voltage. So the maximum power dissipation that can be allowed in a Zener is the Zener voltage multiplied by the current flowing through it. For example, if a 12V Zener passes 12 V DC and 100 mA current, its power dissipation will be 1.2 Watts. So a Zener diode rated 1.3W should be used. The drawback of the Capacitor power supply includes No galvanic isolation from Mains.So if the power supply section fails, it can harm the gadget. Low current output. With a Capacitor power supply. Maximum output current available will be 100 mA or less.So it is not ideal to run heavy current inductive loads. Output voltage and current will not be stable if the AC input varies.

what is need of filter and how many types of filter?
 
01:56
hello friends! How are you? In this video, i have explain filter with a easy anad simple example. hope you have understood easily by this theoritical explanation. in the next vedio i will explain how a clc filter work? so learn to CLC Filter see my vedio on clc filter. Filters: The devices which converts the pulsating DC in to pure DC is called filter. As the name specifies it filters the oscillations in the signal and provides a pure DC at the output. The electronic reactive elements like capacitor and inductors are used to do this work. TYPE OF FILTER: 1. Inductive Filter (L) The property of the inductor is that it opposes any sudden change that occurs in a circuit an provides a smoothed output. In the case of AC, there is change in the magnitude of current with time. So the inductor offers some impendence (opposing force) for AC ((XL = jwL) and offers shot circuit for DC. So by connecting inductor in series with the supply blocks AC and allows DC to pass. 2. Capacitor Filter The elegant quality of the capacitor is it stores the electrical energy for short time and discharges it. By controlling the charging and discharging rate of the capacitor the pure DC can be obtained from the pulsating DC. In simple the capacitor allows AC and blocks DC, so the capacitor can connect parallel to the power supply so that the AC is filtered out and DC will reach the load. 3. LC Filter In the above two filters the reactive components are singly connected, however no element will be perfect in doing the job i.e. inductor in series may pass small quantity of AC and Capacitor in parallel may not block all the AC component. So for better filtering two components are connected as filter which provides less ripple factor at the output compared to the above filter. 4. CLC or π filter In L and LC filter the inductor connected in series to the power supply drops more AC voltage which reduces the efficiency. So to avoid this increase the efficiency a capacitor is connected at the input of the LC filter. The input capacitor charges & discharges and provides a ripple DC at the input of inductor. Then the drop at the inductor is less and provides a ripple less DC which again filtered by capacitor at the output. Multiple connection the above filter provides better efficiency and less ripple factor at the output. *And FOR showing more video about electronic,mathmatical,thermodynamics,mechanics physics and other branches to SUBSCRIBE my channel ''fiZkisFromZero'' subscription link : www.youtube.com/channel/UCc1k6vQ9R-vn0pOPfVf6eIg?view_as=subscriber YOUTUBE SITE : WWW.YOUTUBE.COM/C/fiZkisFromZero

Power Supplies Part 2:  Full Wave Rectification
 
17:07
In this Part 2 of the Power Supply video series, I present a brief review of Part 1 and then explain the theory of Full Wave Rectification. In the second half of the video, an oscilloscope is used to present a step-by-step visual overview of the entire rectification process, including the smoothing of ripple with an electrolytic capacitor. I apologize for the camera's difficulty in focusing on the scope CRT, but hopefully it will not detract from the informative content of the presentation. Link to the video explaining how the filtered DC output can be much higher than the RMS rating of the power transformer: https://youtu.be/MXgG-0MIBGA Thanks for watching. Be sure to stay tuned for Part 3, which will be on Full Wave Bridge Rectification.

How to rectify alternating current into direct current
 
19:05
How to rectify alternating current into direct current In this video we look at two methods of rectifing AC into DC for use in low voltage electronics. We examine half & full wave rectification, but in this video we do not discuss filtering, only rectification theory. I used my new phone to record this. I like the video, but the audio is awful.

Simple 12V to 30V boost 200W inverter converter | How to make Simple 12V to 30V boost 200W inverter converter | How to make Simple 12V to 30V boost 200W inverter converter | How to make A boost converter (step-up converter) is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element: a capacitor, inductor, or the two in combination. To reduce voltage ripple, filters made of capacitors (sometimes in combination with inductors) are normally added to such a converter's output (load-side filter) and input (supply-side filter).

DC - DC Converter  Failure analysis - Electronic Repair
 
08:05
This DC converter had worked for about one year before failing. It was powering an antenna and Ethernet switch which drew around 0.5 Amp.The input voltage was nominally 12 volts from a solar panel and the output 24 volts. The converter is based on the common UC3843 chip.With no load the unit operates OK with 24 volts output. As soon as the load is applied the output voltage drops. On visual inspection the problem appears to be the input capacitor. Examining the capacitor under a microscope confirms it is damaged. The capacitor is also tested with a capacitance meter and an ESR meter. The capacitor is replaced and the converter tested for correct operation.

In this eleventh video 'About Radio' I talk about how to clean the variable tuning capacitor. A bit of a deviation from the circuit diagram but I saw this tip of using a feather to clean the vanes of a capacitor in an old radio book many years ago and through I'd share it with you. If this helps you please let me know. Kind regards ...

19:33
This video includes half-wave rectifier, full-wave center tapped rectifier, full-wave bridge rectifier and capacitor filter, inductor filter and Pi filter. RECTIFIER CIRCUIT The circuit which converts AC in DC is called Rectifier Circuit. There are two types of Rectifier Circuit: 1. Half Wave Rectifier 2. Full Wave Rectifier The unwanted AC-components at the output of Rectifier can be filtered using filter circuits. The smooth the output voltage of Rectifiers, Filter Circuit are used. The output of a Rectifier is not a pure DC, it is still having some AC components that we need to filtered out. This AC component removal action is done by Filter Circuit.
