摘要：
This work analyses the conducted ENU generated by an inverter-fed induction motor drive system with the pulse with modulation (PWM) as one of the most difficult current technical problem which limits power electronics drive's evolution. The analysis of the impedance characteristics of the converters load (motor and cable) is fundamental to interpret the common and differential mode of emission spectra of the converter. The over-voltage and conducted EMI problems in much application with high power motor and long cable can be clarified by load impedance analysis. The impedance analysis allow to determine the high frequency range where a modeling transmission line based model is evidently necessary, instead of much more simple circuit model.
