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.
