Snubber circuit design for high frequency-switched converters using MOSFET as a power device assumes different dimension as regards the minimisation of the power dissipation in the snubber resistance. This paper shows a different mode of operation to reduce the clamp voltage across the device used in...
RC snubber works by modifying the ringing frequency as well as lowering the voltage spike level. The capacitor acts as charge storage and the resistor provides a discharge path. For instance in below circuit, the RC snubber R1 and C1 protects the MOSFET Q1 from voltage spike on the drain. W...
