| Abstract: | A typical PWM variable-speed AC motor drive is studied in order to investigate the conducted electromagnetic interference(EMI) at both the input and output sides of the drive.High frequency equivalent circuit for the drive system which the cable are shielded are proposed.The noise path required parasitic components extraction are implemented through theoretical analysis and experimental method.High frequency EMI source models are presented to consider PWM switching rise-time modeling.The overall circuit models for common-mode EMI prediction are obtained.The proposed method is verified by comparing the predicted spectrum with experimental tests. |
