With automobiles getting more and more electrified, there are a large number of different applications where dc/dc-converters have to be placed. In new electric vehicle concepts it is necessary to connect two different voltage levels with galvanic isolation and assure power transfer with high efficiency over a wide load range. The presented paper describes a new approach to improve the advantages of the well known phase shift zero voltage switching (ZVS) converter to meet efficiency and volume requirements.
