Abstract

An improved passive lossless turn on/off snubber is proposed where energy trapped in the snubber is transferred to both the DC rail and the load. A wider operational range of load current, a higher switching frequency and lower peak switch current make this circuit more practical than conventional lossless snubbers. Design equations, simulations based on a simplified IGBT model and practical results are given.
