摘要：

The development of 50kW converter system using SiC MOSFET is proposed in this paper. SiC MOSFET can operate with lower conduction losses and switching losses, compared with conventional silicon-based MOSFETs. The 50kW battery charger consists of two 25kW AC/DC modular converters and four 12.5kW DC/DC LLC converters. The implementation of SiC MOSFET enables to design AC/DC converters and LLC converters with high-efficiency and high-power density. The performance of proposed converters is validated through simulations and experimental results. The maximum efficiency of AC/DC and DC/DC converter are 99% and 97.9% respectively.
