【Abstract】 A novel method for measuring the conducted EMI feature of an off line converter is proposed. By this measurement, the equivalent conducted EMI sources and internal impedance can be easily educed so as to guide the design of EMI filter effectively. The measurement principle and procedure are described in detail and the method is verified by experiment of an off line AC/DC converter.更多还原
