摘要
Recently, the class of electric vehicles (EVs) with highpower (250 kW) motor drive systems and high energy/high voltage (100 kWh/800 V) batteries has been the prominent focus of various automotive makers. Considering the drive system efficiency, motor acoustic noise, system fail-safe features, and cost, the dual inverter with a dual battery and an open-winding interior permanent magnet motor is considered to be a highly promising drive system configuration for premium class EVs. Therefore, considering the high drive system efficiency and low motor acoustic noise, the authors propose selecting different pulse width modulation (PWM) switching pattern modes in the frequent vehicle operating area based on the vehicle driving modes for the system configuration of premium class EVs. The authors performed suitable simulations and experiments with a 65 kW motor drive system. The experimental results are validated to verify the effectiveness of selecting different PWM switching modes based on the vehicle driving pattern.
