摘要

本文从成本和效率两方面对基于碳化硅MOSFET和基于IGBT的电动汽车牵引逆变器进行了比较。在PSIM中对Cree公司的SiC MOSFET CCS50M12CM2 (1200V / 50A)和Powerex公司的IGBT PM50RL1A120 (1200V / 50A)进行了详细建模，得到了逆变器在不同负载条件下的效率曲线。利用电动汽车在三种不同驱动循环下的运动学模型来评估所得的效率曲线，以比较这两种逆变器在能效方面的性能。最后对这两种逆变器的初始成本和运行成本进行了分析。

Comparison of silicon carbide MOSFET and IGBT based electric vehicle traction inverters

This paper compares Silicon Carbide (SiC) MOSFET and IGBT based electric vehicle (EV) traction inverters by considering the cost and efficiency of these two inverters. Commercially available SiC MOSFET CCS50M12CM2 (1200V / 50A) from Cree and IGBT PM50RL1A120 (1200V / 50A) from Powerex are modeled in detail in PSIM to obtain efficiency curves of inverters under different load conditions. The gained efficiency curves are evaluated using a kinematic model of an EV under three different drive cycles to compare the performance of these two inverters in terms of energy efficiency. Finally, initial cost and operation costs of these two inverters are analyzed.
