Snubbers play an important role in switch-mode power supplies. To understand use of the snubber, we have to look at the performance of a switch-mode power supply. Fig. 1. RCD and R2CD snubbers for ON ...
Power supplies that use diodes to rectify an ac voltage to obtain a dc voltage must deal with inherent inefficiencies. A standard diode or ultra-fast diode can have a 1-V forward voltage or higher at ...
