Abstract
A method of controlling an electric motor includes determining a PWM control signal, analyzing the PWM control signal to determine if components of the PWM signal are within a threshold amount of each other, applying duty-cycle blanking to the PWM control signal, if the components of the PWM control signal are within the threshold amount of each other, to generate an adjusted PWM control signal, and controlling the electric motor with the adjusted the PWM signal to limit parasitic effects.
