This paper describes a newly developed soft-switching DC-DC converter with wide output voltage operations for high voltage battery charger. The proposed converter is designed with zero-voltage-switching (ZVS) techniques and integrated magnetic component. The operational principles, design details and performance of the converter are discussed along with soft-switching characteristics and load transients through experimental waveforms. The converter achieved about 96% efficiency over wide 3.3kW load conditions.
