Abstract

In this paper, a novel zero-voltage-switching (ZVS) current-source rectifier (CSR) based bidirectional on-board charger (OBC) system is proposed for electric vehicles with silicon carbide (SiC) devices. Compared with the traditional voltage-source converter based counterparts, the proposed method offers the advantages including higher-quality output voltage waveforms, enhanced short-circuit-current tolerant capability and longer operation lifetime. Furthermore, ZVS can be achieved for main power switches in CSR with the additional auxiliary power branch. Thus, the switching losses can be further decreased. Besides, the high dv/dt caused by high speed switching SiC devices can be reduced with the capacitor in the auxiliary circuit. Hence, the EMI of high-frequency switching of SiC devices can be mitigated effectively. Both simulations and experimental results are presented to verify the performance of the proposed method.
