| Abstract: | The turn-off characteristic of SiC MOSFET is one of the main contents of the research on transmission efficiency and electrical stress of wireless charging systems, which is important for the safe and efficient operation of the systems. Firstly, the turn-off transient current is modeled for the wireless charging system considering the higher harmonics, and the turn-off energy loss model of SiC MOSFET is established based on the datasheet of MOSFET. Secondly, the correctness of the turn-off transient current is verified by calculation and simulation, and the relationship between the turn-off transient current, turn-off energy loss and DC bus voltage and output power is discussed. Finally, a 1 kW LCC-S compensated wireless charging system based on SiC MOSFET is built for experimental verification. Experimental results show that the SiC MOSFET used in the wireless charging system has the characteristics of constant turn-off transient current and constant turn-off loss in the full output power range. |
