Common mode EMI prediction and research in induction motor for electric vehicles
This paper presents an equivalent circuit of high frequency voltage-controlled switch model of IGBT, and a surge voltage absorption circuit as well. This model can not only significantly reduce the surge voltage, decrease EMI noise, but also obviously inhibit common mode voltage towards the DC power mains.
