摘要

阐述了SiC器件和Si器件的开关特性和能耗对比；根据轨道交通牵引工况计算比较了SiC器件和Si器件的功率损耗；针对高开关频率应用，进行了包括温升、噪声、损耗、效率等一系列试验验证。试验结果表明，采用SiC MOSFET的牵引逆变器可以有效降低电机的谐波损耗，实现牵引系统节能降耗，并降低中低速段的电机噪声。

Abstract

The switching characteristics and energy consumption of SiC devices and Si devices were compared; the power losses of SiC devices and Si devices were compared according to the calculation of traction conditions of rail transit; for the application of high switching frequency, a series of tests including temperature rise, noise, power loss and efficiency were carried out. The test results showd that the traction inverter with SiC MOSFET can effectively reduce the harmonic loss of the motor, realize the energy saving and consumption reduction of the traction system, and reduce the motor noise in the middle and low speed sections.
