摘要
为满足轨道交通高频化、小型化、轻量化、高功率密度的发展需求,在此研究一种基于高压全碳化硅(SiC)金属氧化物半导体场效应晶体管(MOSFET)器件的轨道车辆辅助逆变器。采用某型号SiC器件建立20 kW试验平台,验证SiC器件运行的可行性与稳定性,并通过对比SiC器件与硅(Si)器件性能,证明SiC器件的高效性。
In order to meet the development requirements of high frequency,miniaturization,light weight and high power density of rail transit industry,a kind of rail car auxiliary inverter based on high-voltage silicon carbide(SiC)metal oxide semiconductor field effect transistor(MOSFET)devices is studied.A 20 kW experimental platform is built with SiC devices,which verifies the feasibility and stability of the SiC MOSFET.And the high efficiency of SiC devices is proved by comparing the experimental performance of SiC devices and silicon(Si)devices.
