Abstract
In this paper a design optimisation procedure for a new active resonant snubber topology, specifically suited for high power IGBT converters, is introduced. After the basic operation principles and certain implementation consideration are discussed, the optimisation strategy, based on an analytical loss evaluation, is described. Experimental results obtained on an IGBT phase-arm fitted with an optimally designed snubber are presented
