Abstract

This paper presents a planar transformer design of a 3-kW 250 kHz SiC-based Auxiliary Power Module (APM) with 3.6 kW/L power density for electric vehicle (xEV) application. The transformer design is optimized based on the trade-off between footprint and magnetic loss using the proposed figure-of-merit (FoM) based optimization. In order to increase the ZVS range of the converter, an additional leakage inductance is implemented using the proposed magnetic integration technique. A comparison between non-integrated and integrated magnetic cores using finite element analysis (FEA) is presented. Results show that the integrated structure can reduce the core loss up to 35% and footprint around 15 % compared to the non-integrated. Experimental results show that all the switches can achieves ZVS under the entire load condition.
