Abstract :
In this paper, an analytical method is presented to characterize the conducted EMI performance of inverters. Based on the method, a simple model to predict conducted EMI of inverters is proposed. This model has been experimentally verified in a soft-switching and a hard-switching inverter. The mechanism of EMI improvement and limitation of a soft-switching inverter is discussed
