Abstract

This paper introduces an isolated DC-to-DC converter which features half of the input voltage across the switches, zero-voltage-switching, operation at constant frequency and regulation by pulse-width-modulation. The converter is an alternative to the full-bridge ZVS-PWM DC-to-DC converter in high voltage and high power applications. The complete operating principle, theoretical analysis, relevant equations and design example are provided in this paper. The experimental results of a 1.5 kW converter with 60 V, 25 A output, 600 V input, operating at 50 kHz switching frequency are presented and discussed
