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 insulated gate bipolar transistor (IGBT) model and practical results are givenKeywords
