Abstract

This paper presents a soft-switching boost converter with a flyback snubber for high power applications. The proposed converter configuration can achieve both near zero-voltage and zero-current soft-switching features, while it can reduce the current and voltage stresses of the main switch. In this paper, several passive and active snubbers associated with boost converters are first reviewed, and their limitations are then addressed. One of the boost converters with a flyback snubber is proposed and analyzed in detail to explain the discussed features. Experimental results obtained from a 5-kW boost converter have confirmed that the proposed converter configuration is attractive and feasible for high power applications.
