Title: Research Status of Conducted Common Mode EMI Restraint Method in PWM Motor Drive System
Abstract: PWM motor drive system is widely applied to industrial domain.However,owing to power converter adopts pulse width modulation,which inevitably causes conducted common mode EMI.Harmful degree of common mode EMI is much greater than that of differential mode EMI,so common mode interference is the research focus of EMI.The study status and development trend of conducted common mode EMI suppression technology of PWM motor drive system was analyzed and the deficiency of typical suppression method was presented.
