in this video i explained What is RCD snubber circuit, why it is used in smps switch mode power supply circuit & how it works in high frequency transformer in switch mode power supply. circuit is explained in english language. Educational tutorials on power electronics RCD (resistor capacitor diode SNUBBER Circuit | What is Snubber Circuit and How to Calculate | Explained in Urdu. during switching the high frequency transformer the voltage stress on collector of the mosfet or transistor is double to the vdc and Leakage inductance spikes are also increase, these can be minimized by addition of a snubber circuit (a capacitor, resistor, and diode combination) connected to the transistor collector to positive supply line. it damps the oscillation effect in the off time period of the switching cycle. in this way the the reverse voltage generated in off time are diverted to this RCD snubber circuit so the voltage stress is minimized and the huge power loss in fall time is reduced to a negligible value. Watch this video in Urdu / Hindi https://youtu.be/xyQ2Xde9Z94 this is to design discontinuous flyback Switch Mode Power Supply after watching this series of videos you will be able to:- how to #design #calculate #smps how to understand smps design calculations for discontinuous flyback function of switch mode power supply, in this tutorial i draw the circuit diagram and placed components and made wiring of the components. how to repair switch mode power supply when short circuit at input how to calculate dc buss bar / rail and bulk / main dc / filter capacitor hoe to select minimum maximum voltage for SMPS how to design buck boost converter / half bridge / full bridge / forward / feed forward / zero volt switching ZVS / zero current switching ZCS / flyback converter
