一种用于SiC电机驱动的低损耗紧凑型反射波抑制器

The overvoltage caused by reflected wave phenomenon in motor drives becomes worse with the application of SiC devices due to the significantly higher dv/dt compared with that of Si devices. This letter presents a low-loss and compact active reflected wave canceller (ARWC) to suppress the overvoltage at the motor terminal. The proposed ARWC circuit uses low current devices to break the rising and f...
