Design of Bidirectional Isolated DC/DC Converter Based on SiC Device

Because SiC MOSFET has excellent performance, this paper designs an isolated bidirectional DC/DC converter based on SiC MOSFET. Firstly, the paper analyzes the driving circuit of SiC MOSFET used in this paper, and tests the SiC MOSFET and its driving with double pulse. Then introduces the topology of the converter, analyzes the working principle, and introduces the control strategy adopted by the converter. The simulation model was built in MATLAB to verify the feasibility of the system. Finally, it is verified by experiments that the converter can run normally and realize related functions.
