SPICE simulation in time-domain of the CISPR 25 test setup for conducted emissions in electric vehicles

Abstract

This paper demonstrates the feasibility of SPICE simulation in time-domain of the CISPR 25 test setup to predict the conducted emission phenomenon generated by the inverter in electric vehicles. This is made possible by suitable selection and integration of heterogeneous unit-level circuit models, separately developed and validated in the recent technical literature to represent functional and/or high-frequency phenomena involved in the operation of the battery, the inverter, and the permanent-magnet synchronous motor, as well as in the propagation of conducted noise along the shielded cables of the power bus.
