Analysis and design of resonant dc/dc converters for automotive applications

Abstract

With automobiles getting more electrified, DC-DC resonant converters are developed with renewed interest. Since, it is desirable to reduce the size of power supplies and the higher switching losses through zero-voltage switching (ZVS) feature. This thesis provides detailed information on designing LLC and bidirectional CLLC resonant converter topologies as well as the simulation of four typical converters in automotive applications. Furthermore, the hardware design and manufacture of an EV auxiliary power supply prototype is implemented.
