Rc Snubber. Rc stands simply for resistor r and capacitor c which are connected across a switch. Rc snubbers smps snubbers are energy absorbing circuits used to suppress the voltage spikes caused by the circuit s inductance when a switch electrical or mechanical opens.

An appropriately designed rc snubber can be used with either dc or ac loads. R will limit the forward dv dt and r1 limits the discharge current of the capacitor when transistor q1 is turned on. 10 again we must choose which value of fcto be used and there is no single correct answer to this question.
The most common snubber circuit is a capacitor and resistor connected in series across the switch transistor.
Rc stands simply for resistor r and capacitor c which are connected across a switch. Simple rc voltage snubber. This article explains why a snubber is needed for power switches. It is used on output inductors and the secondaries of transformers as well as across diodes and switches.
