When Q2 is turned on, current commutates to the blue loop and the reverse recovery effectoccurs in Q1. We observe the effect of Q1 reverse recovery on the VDS waveform of Q2; see Fig.
Designing RC snubbers 1. Introduction This document describes the design of a simple “RC snubber circuit”. The snubber is used to suppress high-frequency oscillations associated with reverse recovery effects in power semiconductor applications. 2. Test circuit The basic circuit is a half-bridge and shown in Fig. 1. aaa-002741 VCC VDD 0V Q2 ...
