Please help improve this section by adding citations to reliable sources. Unsourced material may be challenged and removed. (October 2017) (Learn how and when to remove this template message) See also: Rectifier § Rectifier output smoothing With AC input, the output of a diode bridge (called a full-wave rectifier for this purpose; there is also half-wave rectification, which does not use a diode bridge) is polarized pulsating non-sinusoidal voltage of the same amplitude but twice the frequency of the input. It may be considered as DC voltage upon which is superimposed a very large ripple voltage. This kind of electric power is not very usable, because ripple is dissipated as waste heat in DC circuit components and may cause noise or distortion during circuit operation. So nearly all rectifiers are followed by a series of bandpass or bandstop filters and/or a voltage regulator to convert most or all of the ripple voltage into a smoother and possibly higher DC output. A filter may be as simple as a single sufficiently large capacitor or choke, but most power-supply filters have multiple alternating series and shunt components. When the ripple voltage rises, reactive power is stored in the filter components, reducing the voltage; when the ripple voltage falls, reactive power is discharged from the filter components, raising the voltage. The final stage of rectification may consist of a zener diode-based voltage regulator, which almost completely eliminates any residual ripple.

Simple Diode Protection Circuits in Rectifiers ...
 
02:02
Simple Diode Protection Circuits in Rectifiers of Transformer Power Supply Sources As a rule build-up of filter capacitors are used in order to bring the voltage ripple level in transformer power supply units to as low as possible. This is not the most efficient method, as at the time of connection the uncharged filter capacitors as a whole act as the short circuit for the rectifier diodes and the secondary transformer winding. To limit the charge current of the filter capacitors, constructors often use current-limiting components that in the majority of cases get disconnected automatically. One of the examples here is the parallel rectifier diode protection circuit, where capacitance 1 is connected in series to the resettable fuse. The second option is the series diode protection circuit. In this case capacitors 1 and 2 are separated by the resettable fuse. As result of the current pulse, these protection fuses temporarily disconnect the entire capacitors circuit, and then connect again in a certain amount of time. The third circuit is diode protection at connection. Here a current-limiting resistor is added between the diodes and the filter capacitors. Mounted in parallel to the resistor is a resettable fuse that is designed for the maximum current flowing through the rectifier diodes. With a pulse of the charge current, the fuse resistance increases, and the capacitors get gradually charged through the current-limiting resistor. Later the resistance of the fuse decreases. At the same time, resetting fuses protect the rectifier elements from overcurrent and short circuits.

Finding the Performance Parameters of The Half Wave Rectifier
 
09:34
Introduction : We can judge the performance of HWR (Half Wave Rectifier) by the Ripple Factor (RF) Parameter. RF is parameter to measure AC & DC component. RF Significance in case of Rectification: The less the Vac i.e. the AC component of the Voltage, the more the more good the rectifier. RF for all waves as: Ripple Factor(RF)=(AC component of Voltage (Vac) )/(DC component of Voltage(Vdc)) Idealialy: RF = 0 i.e. the Vac = 0 and Vdc ≠ 0 RMS Value : Its defined as the DC equivalent value in AC circuit i.e. 0.707 0r ((1)⁄(√2)) V DC in AC Circuit = 1 V in DC Circuit.

Halfwave Rectifier Experiment | How the connections are made | Finding the ripple factor
 
01:42
Here described how the connections are made for finding the ripple facor of a halfwave rectifier. We need a step down transformer, resistors, capacitor, bread board, digital multimeter, and a power supply 1.A rectifier is a circuit which converts the Alternating Current (AC) input power into a Direct Current (DC) output power. The input power supply may be either a single-phase or a multi-phase supply with the simplest of all the rectifier circuits being that of the Half Wave Rectifier. 2.A widely used application of this feature and diodes in general is in the conversion of an alternating voltage ( AC ) into a continuous voltage ( DC ). In other words, Rectification. But small signal diodes can also be used as rectifiers in low-power, low current (less than 1-amp) rectifiers or applications, but where larger forward bias currents or higher reverse bias blocking voltages are involved the PN junction of a small signal diode would eventually overheat and melt so larger more robust Power Diodes are used instead. The power semiconductor diode, known simply as the Power Diode, has a much larger PN junction area compared to its smaller signal diode cousin, resulting in a high forward current capability of up to several hundred amps (KA) and a reverse blocking voltage of up to several thousand volts (KV). Since the power diode has a large PN junction, it is not suitable for high frequency applications above 1MHz, but special and expensive high frequency, high current diodes are available. For high frequency rectifier applications Schottky Diodes are generally used because of their short reverse recovery time and low voltage drop in their forward bias condition. Power diodes provide uncontrolled rectification of power and are used in applications such as battery charging and DC power supplies as well as AC rectifiers and inverters. Due to their high current and voltage characteristics they can also be used as free-wheeling diodes and snubber networks. Power diodes are designed to have a forward “ON” resistance of fractions of an Ohm while their reverse blocking resistance is in the mega-Ohms range. Some of the larger value power diodes are designed to be “stud mounted” onto heatsinks reducing their thermal resistance to between 0.1 to 1oC/Watt. If an alternating voltage is applied across a power diode, during the positive half cycle the diode will conduct passing current and during the negative half cycle the diode will not conduct blocking the flow of current. Then conduction through the power diode only occurs during the positive half cycle and is therefore unidirectional i.e. DC as shown. 3. Half Wave Rectification A rectifier is a circuit which converts the Alternating Current (AC) input power into a Direct Current (DC) output power. The input power supply may be either a single-phase or a multi-phase supply with the simplest of all the rectifier circuits being that of the Half Wave Rectifier. The power diode in a half wave rectifier circuit passes just one half of each complete sine wave of the AC supply in order to convert it into a DC supply. Then this type of circuit is called a “half-wave” rectifier because it passes only half of the incoming AC power supply as shown below. 4. During each “positive” half cycle of the AC sine wave, the diode is forward biased as the anode is positive with respect to the cathode resulting in current flowing through the diode. Since the DC load is resistive (resistor, R), the current flowing in the load resistor is therefore proportional to the voltage (Ohm´s Law), and the voltage across the load resistor will therefore be the same as the supply voltage, Vs (minus Vf), that is the “DC” voltage across the load is sinusoidal for the first half cycle only so Vout = Vs. During each “negative” half cycle of the AC sinusoidal input waveform, the diode is reverse biased as the anode is negative with respect to the cathode. Therefore, NO current flows through the diode or circuit. Then in the negative half cycle of the supply, no current flows in the load resistor as no voltage appears across it so therefore, Vout = 0. The current on the DC side of the circuit flows in one direction only making the circuit Unidirectional. As the load resistor receives from the diode a positive half of the waveform, zero volts, a positive half of the waveform, zero volts, etc, the value of this irregular voltage would be equal in value to an equivalent DC voltage of 0.318 x Vmax of the input sinusoidal waveform or 0.45 x Vrms of the input sinusoidal waveform. Then the equivalent DC voltage, VDC across the load resistor is calculated as follows.

Experiment #5 - Full Wave Carbon Fibre HHO Bridge Rectifier Demonstration
 
11:39
A demonstration of my new full wave bridge rectifier producing HHO in considerably larger quantities. This new rectifier requires only two standard diodes to produce a 12VDC output with a ripple voltage of less than 1V. This circuit consumes approximately 100 Watts from a 240VAC mains power supply. Power consumption is determined by three things: 1. Conductivity of the water/amount of electrolyte (electrolyte is optional) 2. Frequency of the AC input signal. 3. Total surface area of the electrodes producing the HHO. I will conduct further experiments with various high frequency AC input signals (including modified sine waves) to see if HHO production can be increased.

find out a choke coil for a DC power supply on 50/60 Hz or other freq. (basics)
 
08:49
MORE INFO&LINKS IN THIS TEXTBOX. WARNING: some oscilloscopes can NOT handle 300 Volt at their input. These scopes will immediately be defective! So read the manual from your oscilloscope to find out the maximum input voltage on the probe! When it is low, use a voltage divider at the output from the circuit (1 M- 10K) and connect the probe from the scope at the node -low voltage point- from the voltage divider). This video (somewhat too long, sorry, I repeat myself too much) shows how you can find out a choke coil in a PI filter configuration that damps out the 50 Hz or 60 Hz from the standard mains supply in Europe, US, elsewhere. Value from 50 uF relates to 50 Hz or 60 Hz systems. Succes in a real/concrete situation depends on experiments (!) with old /unused/thrownaway ferrite core coils or old transformers (iron lamellae cores) in the 10 Watt range made for 110 V or 230 V 50 Hz or 60 Hz AC.With simple resources, e.g. the old AC 230V- 110 V AC transformers, self-wound coils on a ferrite rod, old computer power supply filter coils, etc, can be used . You must find it all out (oscilloscope absolutely necessary). With the oscillator you can get an indication about the healthyness and usefulness of old (ferrite core or not) coils. NEVER connect your oscilloscope directly to 100 - 300 V or more (!!). Keep in mind that on power supplies on higher frequencies (40 KHz - 400 KHz) the choke coil and the caps from the Pi filter have to be adapted to the high frequency. In that case no electrolytic capacitors must be used but only non polar plastic caps or ceramic caps (low HF loss). More circuits in my books on the Lulu website, author Ko Tilman, or on the internet. The video that I refer to in this video is: "test oscillator for coils 30 mH-3,6 uH (0,9uH) (e.g.25 KHz-1,2 MHz" published 10 october 2014 BUT (!) Better/also usable are: 1. "FET test oscillator sine wave with very good linearity (200 KHz - 9 MHz)" published 3 october 2015 2. "Device to test radio coils on resonance, optimum frequency and quality" published 25 october 2015. Both circuits are usable. The oscillator published on 25 october 2015 is somewhat more sophisticated (has a broader frequency band, especially on lower frequencies, say 35 KHz - 200 KHz).

This configuration results in each diode conducting in turn when its anode terminal is positive with respect to the transformer centre point C producing an output during both half-cycles, twice that for the half wave rectifier so it is 100% efficient FEEL FREE TO COMMENT BELOW

Types of Rectifiers: 1. Half wave rectifier 2. Full wave rectifier Full wave rectifier has again 2 types as: a. Corner tapped b. Bridge A rectifier is an electrical device composed of one or more diodes that converts alternating current (AC) to direct current (DC). A diode is like a one-way valve that allows an electrical current to flow in only one direction. This process is called rectification. A rectifier can take the shape of several different physical forms such as solid-state diodes, vacuum tube diodes, mercury arc valves, silicon-controlled rectifiers and various other silicon-based semiconductor switches. Rectifiers are used in various devices, including: DC power supplies Radio signals or detectors A source of power instead of generating current As flame rectification to detect the presence of flame High-voltage direct current power transmission systems Several household appliances use power rectifiers to create power, like notebooks or laptops, video game systems and televisions. A rectifier is an electrical device that converts AC to DC. AC occasionally reverses direction and DC flows in one direction only. Rectification produces a type of DC that encompasses active voltages and currents, which are then adjusted into a type of constant voltage DC, although this varies depending on the current's end-use. The current is allowed to flow uninterrupted in one direction, and no current is allowed to flow in the opposite direction. Almost all rectifiers contain more than one diode in particular arrangements. A rectifier also has different waveforms, such as: Half Wave: Either the positive or negative wave is passed through and the other wave is blocked. It is not efficient because only half of the input wave form reaches the output. Full Wave: Reverses the negative part of the AC wave form and combines it with the positive Single-Phase AC: Two diodes can form a full-wave rectifier if the transformer is center-tapped. Four diodes arranged in a bridge are needed if there is no center-tap. Three-Phase AC: Generally uses three pairs of diodes One of the key problems with rectifiers is that AC power has peaks and lows, which may not produce a constant DC voltage. Usually, a smoothing circuit or filter needs to be coupled with the power rectifier to receive a smooth DC current.""

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.

Hello people, welcome to ‘It’s All About Electronics’ you tube channel. Here we will learn all about electronics and do experiments based on our gained knowledge. Electronics is a very vast subject like an ocean. We will not restrict ourselves to learn only some specific topics of this subject, rather than that we will try to learn all the general as well as the advanced topics of this subject. So without any further delay let’s start today’s session. YouTube channel URL → https://www.youtube.com/channel/UCavb... Let’s start today with a very well-known and simple circuit known as Choke Input or L Section Filter Circuit for Full Wave Rectifier Circuit Using Diode ’. Rectifier is an electronic device which converts the alternating current to unidirectional current, in other words rectifier converts the AC voltage to DC voltage. Rectifier filter is an electronic circuit that removes ripple or unwanted AC signal components from the output of a Rectifier. When we pass pulsating DC (Pulsating DC is a DC signal comprises of unwanted AC component known as ripples. ) through a L Section Filter, it will able to remove ripples from the output and will smooth the output signal. So let’s start with this circuit. First we will understand theoretical aspects of L Section Filter, means we will understand the circuit diagram, do little derivation based on its circuit design and output waveform and then we will do practical session using LTspice. LTspice is the best free simulation software supported by Linear Technology. The download and installation of LTspice is very easy and needs very less time.
