Abstract

This paper describes a practical design and control of a newly developed zero-voltage-switching (ZVS) 3-level dc-dc converter with minimum circulating current. The converter is designed with ZVS soft-switching techniques to achieve high efficiency. Furthermore, two main key issues on the high voltage dc-dc converter are discussed with minimization of the circulation current between main switches and optimal dead time for soft switching. The converter has achieved about 95% efficiency under wide 7 kW load condition.
