Abstract
A method of operating a power inverter for an electric machine includes selecting an inverter switching technique; determining a frequency range for inverter switching; determining a direct current (DC) voltage range for inverter switching; determining an optimal switching map including an inverter switching technique and frequency selection for each value of torque-speed on a torque-speed curve; and controlling switches included in the power inverter using the optimal switching map.
