Abstract
Electromagnetic interference is a major challenge in the current design of electric vehicle motor drive systems. In order to verify the effectiveness and feasibility of electromagnetic interference suppression technology at the early stage of system design, a SPICE equivalent circuit modeling method was proposed for motor drive systems based on port impedance measurement. According to the physical structure of the system components, a high-voltage shielded cable model, a motor controller model, and a drive motor model were established, and the accuracy of the models was verified through experiments. Combining the component models together, a complete motor drive system conducted electromagnetic interference prediction model was constructed. According to GB/T 18655-2016 and GB/T 36282-2018, system load conducted electromagnetic interference simulation and experiments were carried out to verify the accuracy of the model.
