Abstract

In this paper, a hybrid DC-DC boost converter with high voltage gain and a wide duty cycle range was proposed. After detailed analysis of the proposed converter, it was designed. Thanks to the active soft switching applied to the proposed converter, the losses due to hard switching were reduced. While the main switch of proposed converter was turning on, the main switch voltage was nearly zero during current transition and in the opposite case, the main switch current was nearly zero during voltage transition. Thus, the power losses were reduced for both cases when the main switch turned on and off. The simulation results for MOSFET and IGBT based proposed converter with active soft switching were obtained for variable loads.
