Electromagnetic Interference (EMI) Issue is One of the Major Constraints of Power Electronic Converters, Especially for Variable-Speed Systems. in This Work, the Common Mode Noise in a Three-Phase Motor System is Analyzed and Modeled. the Three-Phase Pulse-Width Modulation (PWM) Inverter Creates High Magnitudes of Dv/dt and Di/dt, Resulting in Common Mode Noise and Disturbance Power. in This Paper, the Common Mode Noise and Disturbance Power Modeling Method Are Proposed for Three-Phase Motor Systems. the Proposed Equivalent Circuit Model Comprises Detailed Models for Insulated Gate Bipolar Transistors (IGBTs), EMI Filters, a Three-Phase Motor and a Printed Circuit Board (PCB). the Proposed Model of a Three-Phase System Was Verified by Measurement with and Without Additional Y-Capacitors. the Measured and Modeled Common-Mode Noise Shows a Correlation in Broadband Common-Mode Noise Reduction.
