Abstract

This paper presents a comparison of two potential soft-switching bi-directional high-frequency transformer isolated voltage-fed and current-fed dual active bridge dc/dc converters for fuel cell vehicle application. The comparison and discussion are conducted over the suitability of these two converters acting as a front-end dc/dc converter for a fuel cell inverter from the perspective of the circulating and peak currents, RMS currents through the devices, components' ratings, size, losses, and efficiency. Software package PSIM 9.0.4 has been utilized to justify the merits of current-fed converter over voltage-fed converter for the given application. Experimental results of current-fed converter have also been provided. Switching losses are reduced significantly owing to zero-current switching (ZCS) of primary switches and zero-voltage switching (ZVS) of secondary switches, which allow high switching frequency operation resulting in a compact and low cost system.
