WebDesigning RC snubbers 1. Introduction This document describes the design of a simp le “RC snubber circuit”. The snubber is used to suppress high-frequency o scillations associated with reve rse recovery effects in power semiconductor applications 2. Test circuit The basic circuit is a half-bridge and shown in Figure 1. WebThere are two general rules for snubber parametrization: The time constant of R-C or R L should be several time steps larger than the simulation step. The overall impedance of the snubber on the frequency of interest (usually 50/60Hz) should be sized to introduce small losses in the circuit, typically under 1%.

The diode is a semiconductor device that is controlled by its own voltage Vak and current Iak. When a diode is forward biased (Vak > 0), it starts to conduct with a small forward voltage Vf across it. It turns off when the current flow into the device becomes 0. When the diode is reverse biased (Vak < 0), it stays in the off state.
