Abstract

This paper presents the soft switching mode DC-DC converter using bipolar mode static induction transistor (B-SIT). The proposed DC-DC converter is obtained by soft-switching mode voltage-clamped phase-shifting output voltage controlled half bridge resonant inverter with bridge rectifier. This converter efficiently operates at zero-current soft switching mode in order to minimize switching losses and electrical stresses of the switching device over a wide voltage regulation range. Experimental results of the proposed converter show the conversion efficiency of 94% at a switching frequency of 100 kHz
