A new ZVT-PWM boost converter with active snubber cell

Abstract

In this study, boost converter with a new active snubber cell is proposed. This snubber circuit provides ZVT turn on and ZVS turn off for the main switch. Also, the auxiliary switch turns on with ZCS and turns off with ZVS with this snubber cell. SS operation conditions are maintained at very wide line and load ranges and no semiconductor component has an additional voltage stress. The current stress of the auxiliary switch is reduced through transferring of SS energy to the output. There is no additional current stress on the main switch. In this study, the operating principle of the new ZVT PWM DC-DC converter is presented and its operation is verified with PSpice simulation software for a 1 kW and 100 kHz model.
