Web22 Nov 2024 · 2) Snubber. In order to snub (damp) the resonance, a snubber should be put where the voltage due to the resonance is maximum. So, if you want to use one, the snubber should be put across the transformer secondary. Putting one snubber across each diode is a waste of components, especially if you already put caps across the diodes. Web6 Aug 2014 · Proper design of the snubber can result in higher reliability, higher efficiency and lower EMI. Among many different kinds of snubbers, the resistor-capacitor (RC) snubber is the most popular snubber circuit. This article explains why a snubber is needed for power switches. Some practical tips for an optimum snubber design are provided as well. dr kakani cardiology va beach
