Design of Snubbers for Power Circuits
www.cde.comRC snubber design An RC snubber, placed across the switch as shown in figure 4, can be used to reduce the peak voltage at turn-off and to damp the ringing. In most cases a very simple design technique can be used to determine suitable values for the snubber components (R s and C s). In those cases where a more opti-

assets.nexperia.comDesigning 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 ...
