Abstract :
In this paper, a novel topology of a non-isolated boost converter with zero-voltage-switching (ZVS) capabilities is presented. In order to realize ZVS conditions, the auxiliary circuit only consists of a coupled inductor and a diode, which operates with a zero-current-switching (ZCS) condition. Due to ZVS, the reverse recovery problem of MOSFET anti-parallel body diodes can be resolved, and the voltage and current stresses on the switch components are also reduced. The detailed operating analysis of the proposed converter and the design method of the main circuit are also presented. With the aim to verify the effectiveness and feasibility of the proposed boost converter, the simulation results are also given.
