Samenvatting

This paper introduces a new converter for implementing CC and CV charging strategies for battery electric vehicles by using an isolated full-bridge converter with adding a variable-resonant tank. Thanks to the variable-resonant tank, the proposed converter is able to implement CC and CV control strategies with a fixed-switching frequency and not using any regulation for the primary switches. This capability of non-regulation is achievable due to inherent characteristics (constant-current frequency and constant-voltage frequency) of the variable-resonant tank. Since the proposed converter only operates at these resonant frequencies, it can achieve the ZVS and ZCS for all semiconductor devices. A design optimization framework is used to design the resonant tanks to properly achieve all advantages. To verify the improved performances, a software simulation of 3.3 kW was conducted. The results have shown that the proposed converter can charge the battery with a constant current of 7.8 A, a constant voltage of 420 V at a fixed frequency of 50 kHz.
