Abstract
This paper investigates the system-level conducted EMI model for SiC powertrain of electric vehicles. Firstly, a conducted EMI model for the whole powertrain is presented, which includes battery, inverter, PMSM, AC cables and DC cables. Then, a conducted emission test platform for EV powertrain is built to verify the system-level EMI model. Finally, impact of system layout on EMI noise, including AC cable length, grounding schemes of AC and DC cable shielding layers, PWM schemes, and auxiliary power supply are investigated according to both proposed system-level EMI model and experiment test results.Keywords
