摘要：
This paper presents a new approach for modeling of the conducted electromagnetic interference (EMI) prediction for widely used converter systems. Coupling paths and mechanism of differential mode (DM) interference and common mode (CM) interference have been analyzed. Models to predict the high-frequency noise of PWM converter system are created. A direct calculation method in frequency domain is proposed for the deduction of frequency spectrum. A method is given for obtaining the parasitic parameters and topological structure of the model. An experimental investigation of the conducted emission from an actual high-power rectifier system is described. The validity of the models is confirmed by comparison to laboratory measurements.
