Abstract

This paper presents a novel transformer isolated parallel connected qZ-source full-bridge dc-dc converter using coupled inductor in both the qZ-source network and the output filter inductor. Unlike the traditional voltage-fed or current-fed converters, the proposed converter can be open- and short-circuited without damaging switching devices. Therefore, the desired buck and boost function can be achieved and the converter reliability can be greatly improved. Furthermore, all the bulky inductors in the qZ-source network and the output filter can be minimized with the proposed inductor structures. A 4 kW prototype dc-dc converter is built and tested to verify performances of the proposed converter.
