| Abstract: | Auxiliary converter is an important part of the vehicles in rail transit. Using SiC MOSFETs as the switching devices can improve the power density overall. In this paper, a driver is designed for SiC MOSFET based on the characteristics of the device and the driver is tested under both low and high voltage experiments. The power modules of the converter system are replaced by SiC MOSFET completely and the surrounding passive components are optimized. The power loss calculation model is established based on the topology of the converter and the model is validated by simulation. A comparison of power loss for the original converter and the converter using SiC MOSFETs is made. |
