Abstract :
This paper deals with the problem of conducted electromagnetic interference (EMI) emission produced by pulse width modulation (PWM) inverter system. It is determined that the inverter system generates considerable impulse current through the power leads feeding the system resulting in serious EMI problems and significant voltage distortion in the power system. An investigation of conducted EMI emission from (PWM) inverter feeding an induction motor is described. A proposed procedure that can be used to improve the conducted emission of the PWM inverter is presented
