A Linear equivalent circuit model of inverter was proposed for applying to designing EMC filters to reduce the conducted emission from electrical appliances with switched-mode power supplys as inverters and converters. We employed a microwave oven as the equipment under test(EUT)and measured the conducted emission voltage at mains port with a line impedance stabilizing network(LISN). Measured disturbances contained both the differential and common modes and we determined the proposed model to have a circuitry structure composed of differential- and common-mode blocks. We, then, described a simple method to determine model parameters from measurements and decided the parameters with the method. With the proposed model, the conducted emission voltage of the EUT was estimated through circuitry simulation and compared to measurement. The comparison showed that the model predicted performance of the EMI filter in reduction of the conducted emission in practical accuracies at frequencies in which model parameters determined had been reasonable.
