Abstract
A method of operating a motor includes providing an electric system coupled with the motor, the electric system including parallel inverter legs; subjecting the motor to a first interleaving angle when the electric system is under a first condition; and subjecting the motor to a second interleaving angle different from the first interleaving angle when the electric system is under a second condition; wherein the steps of subjecting the motor to the first interleaving angle and subjecting the motor to the second interleaving angle occur within continuous operation of the electric system and the motor.
Claims18
