Circuit building block time. The capacitance multiplier and how it gives almost negligible power supply ripple compared to a voltage regulator. Whiteboard theory and then some bench demonstrations and experiments. Plus a twist at the end that proves that the "Capacitance multiplier" is perhaps one of the most mis-named circuits of all time.

Why Capacitive Power Supply should be avoided
 
11:28
Capacitive Power Supplies are a dirty cheap solution to feed simple low power devices directly from Mains, but the drawbacks are way more than the benefits in many cases. In this video I'll try to show that with a practical experiment. In short, lack of isolation, low efficiency and a power factor close to zero should be the main reasons to suggest electronic engineers to avoid this typology of circuit. In this video I've tested an actual circuit, and described in details how it works and why it is so poor in efficiency and power factor.

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.

ripple factor trick formula/value |Ripple Factor of Half-wave & Full Wave Rectifier | RIPPLE FACTOR

This ac component is undesirable and cause for the pulsations in the rectifier output. So the ac component present in the pulsating output i.e. in the rectifier output is known as Ripple. Ripple Factor:- The ratio of r.m.s. value of a.c. component to the d.c. component in the rectifier output is known as ripple factor i.e. Ripple factor = r.m.s. value of a.c component / value of d.c. component=Iac/Idc The ripple factor is a measure of the quality of the rectification of an AC current. The DC output of an ideal full wave rectifier should be a "straight line" (i.e. the output should have a constant value), but due to imperfections in the rectifier design or implementation the result has "ripples" caused by an undesired AC component. The ripple factor compares the rms value of the AC component with the value of the DC output as an indication of how "deep" those "ripples" are. Ripple factor (γ) may be defined as the ratio of the root mean square (rms) value of the ripple voltage to the absolute value of the DC component of the output voltage, usually expressed as a percentage. However, ripple voltage is also commonly expressed as the peak-to-peak value. Ripple voltage is an alternating (AC) voltage which is a constituent part of a composite voltage waveform with a constant DC component (offset) which may be positive or negative, but for analysis is usually considered to be an absolute value. The ripple component is often small relative to the DC component, but in absolute terms, ripple (as in the case of HVDC transmission systems) may be thousands of volts. Ripple itself is a composite (non-sinusoidal) waveform consisting of harmonics of some fundamental frequency which is usually the AC line frequency of 50/60Hz, but in the case of switched-mode power supplies, the fundamental frequency can be tens of kilohertz to megahertz. The characteristics and components of ripple depend on its source: there is single-phase half- and full-wave rectification, and three-phase half- and full-wave rectification. Rectification can be controlled (uses Silicon Controlled Rectifiers (SCRs) or uncontrolled (uses diodes). There is in addition, active rectification which uses transistors. Various properties of ripple voltage may be important depending on application: the equation of the ripple for Fourier analysis to determine the constituent harmonics; the peak (usually peak-to-peak) value of the voltage; the root mean square (RMS) value of the voltage which is a component of power transmitted; the ripple factor γ, the ratio of RMS value to DC voltage output; the conversion ratio (also called the rectification ratio or "efficiency") η, the ratio of DC output power to AC input power; and form-factor, the ratio of the RMS value of the output voltage to the average value of the output voltage. Analogous ratios for output ripple current may also be computed. An electronic filter with high impedance at the ripple frequency may be used to reduce ripple voltage and increase or decrease DC output; such a filter is often called a smoothing filter. The initial step in AC to DC conversion is to send the AC current through a rectifier. The ripple voltage output is very large in this situation; the peak-to-peak ripple voltage is equal to the peak AC voltage minus the forward voltage of the rectifier diodes. In the case of a SS silicon diode, the forward voltage is 0.7V; for vacuum tube rectifiers, forward voltage usually ranges between 25 and 67V (5R4). The output voltage is a sine wave with the negative half-cycles inverted. #ripplefactor #trick #onlineexamcentre #halfwaverectifier #fullwaverectifier #electrical #concept #technical #edu #engineering #science #physics #technician

DIY Homemade 30watt LED BULB with Transformerless power supply |easy and low cost
 
07:05
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.

Pi filter Ripple calculations.

Electronic filters are circuits which perform signal processing functions, specifically to remove unwanted frequency components from the signal, to enhance wanted ones, or both. Electronic filters can be: Three-element filters can have a 'T' or 'π' topology and in either geometries, a low-pass, high-pass, band-pass, or band-stop characteristic is possible. The components can be chosen symmetric or not, depending on the required frequency characteristics. The high-pass T filter in the illustration, has a very low impedance at high frequencies, and a very high impedance at low frequencies. That means that it can be inserted in a transmission line, resulting in the high frequencies being passed and low frequencies being reflected. Likewise, for the illustrated low-pass π filter, the circuit can be connected to a transmission line, transmitting low frequencies and reflecting high frequencies. Using m-derived filter sections with correct termination impedances, the input impedance can be reasonably

A - The block diagram consists the following components: 1 - Series Resistor or current limiting resistor 2 - X-rated Capacitor 3 - Bleeder Resistor 4 - Bridge Rectifier. 5 - Filter unit 6 - Voltage regulator . series resistor limit the harmonics of switching. X-Rated capacitor is use to step down the voltages and current. Bleeder resistor is used to provide the reverse path of capacitor charges after switch off the power supply. Bridge rectifier is used to convert AC voltage into pulsating DC voltages. the filter unit is used to purifie the DC and the last unit or regulator is used to reduce the variation of the power supply voltages. the formula's are z=((Vrms*1.4142)-Vout)/output current c=1/(2*3.1416*f*xc) here z is the impedance , c is the capacitance , Xc is the capacitive reactacnce of the capacitor and f is the supply frequency . Friendsin today's lecture we will learn about the "Transformerless power supply today i will tell you some secrete formula's by using these formula's you can design your own power supply of required current and voltages i already poste a video about "Transformerless power supply" but some friends have doubts abut transformerless power supply i am making this video for clearing those doubts. table of contents of today's video are as follows. table of contents of today's video are as follows. A- Block Diagram in this section we will see the purpose of different blocks.and we will see which components are use in this block and which component is necessary and which is for protection B -we will see some formula's that you can use for design a power supply of your requirement. C - we will solve an example the example will help you to understand the formula's D - we will perform an experiment E - and then you can ask your questions in comment section , i will answer you . Did you like this video? and what you learn in this video tell me I am waiting. if you like the video thumb up for me we will start form block diagram this is the input voltage section and this is the output voltage section.at this point we will apply input voltage and after step-down we will run this load i use an led and current limiting resistor as a load the first component of this block diagram is a series resistor or current limiting resistor the purpose of this resistor is to protect the x-rated capacitor form switching harmonics. if you don't block these harmonics , this will blow up the x-rated capacitor the x-rated capacitor is the heart of this power supply so we can say the series resistor is the protection of x-rated capacitor we use another resistor in parallel with the capacitor the purpose of this resistor is to provide a reverse path for charges stored in cap. after switch off supply. this resistor is known as Bleeder Resistor after step down the voltage we will use a bridge rectifier the purpose of the bridge rectifier is to convert AC voltage into DC voltages. use a regulator the purpose of regulator is to remove variations which are coming from input.to protect the load form variations. in regulator section we can use zener diode or 78xx series which you can use to find the value of components. these are the simplified formula's 1st formula can be use to calculat the impedance and the 2nd one can be used to find the capacitor value. the most important formula is the 2nd one. actually we use these tow formula's to find the capacitor value. but we need Xc in 2nd formula which we calculte form 1st formula.here the vaue of Z and Xc are same first of all we have rms voltage which are supply voltage if we will say 220 or 230 volts .these are the rms voltages we can't use these voltage for calculation we will convert rms voltage into peak voltages for peak voltages we will multiply with root 2 in this way rms voltages will convert into peak voltages after that we will subtract the required voltage or load v.and then we will divide this with output current make sure the value of Iout will be in ampare if you have mA then convert them in amp befor putting we will do an example of this in a mint. for more information please visit : https://www.youtube.com/c/electricfocus thanks for watching.

Rectifier is an electronic device that converts an alternating current to a direct current by suppression or inversion of alternate half cycles. Rectifiers are most often made of a combination of diodes, which allow current to pass in one direction only. Half wave Rectifier In half wave rectification, the rectifier conducts current only during the positive half cycle of input AC supply. The negative half cycles of AC supply are suppressed no voltage appears across the load. Therefore the current always flows in one direction through the load through every half cycle. Full wave Rectifier A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output by reversing the negative (or positive) portions of the alternating current waveform. The positive (or negative) portions thus combine with the reversed negative (or positive) portions to produce an entirely positive (or negative) voltage/current waveform. For single-phase AC, if the transformer is center-tapped, then two diodes back-to-back (i.e. anodes-to- anode or cathode-to-cathode) form a full-wave rectifier. Full-wave rectification converts both polarities of the input waveform to DC (direct current), and is more efficient. However, in a circuit with a non-center tapped transformer, four diodes are required instead of the one needed for half-wave rectification. This is due to each output polarity requiring two rectifiers each, for example, one for when AC terminal 'X' is positive and one for when AC terminal 'Y' is positive. Ripple Factor The output voltage (or load current) of a rectifier consist of two components namely DC component and AC component. The AC component present in the output is called a ripple. Smaller the ripple more effective will be the rectified. Voltage Regulation Domestic, commercial and industrial loads demand a nearly constant voltage supply. It is, therefore, essential that the output voltage of a transformer stays within narrow limits as load and its power factor vary. The leaky reactance is the chief cause of voltage drop in a transformer and must be kept as low as possible by design and manufacturing techniques. PROCEDURE 1. Connections are given as per the circuit diagram (Half Wave Rectifier) . 2. Note the amplitude and time period of rectified output. 3. Measure Vdc and Vrms. 4. Calculate the ripple factor. 5. Draw the graph for voltage versus time. 6. Repeat the same procedure for Full Wave Rectifier.

The half wave rectifier only passes the one half of the input sine wave (either positive or negative) and rejects the other half. The output of the half wave rectifier is pulsating DC. The ripple in the output waveform can be reduced using the filter. To remove or reduce the ripple from the output waveform, the RC time constant of the filter circuit should be much larger than the time period of the half wave rectifier.

I thought it would be interesting to do a theory video on linear power supply design. I build up a simple low voltage supply to setup the framework for the larger and more powerful split rail linear power supply used by the (Nelson Pass) PassLabs F5 amplifier that’ll show up over the next couple of videos. I begin building up the F5 supply and we compare ripple voltage between a switch mode supply and linear supplies. I also cover how to select the proper filter capacitor with some basic algebra. I went a little nuts with GarageBand an made some techno music to go along with the time lapse build. Not my cup of tea, but it was fun to make anyway! Hope you guys enjoy this LONGER video.
