Abstract
A motor drive system includes at least one current sensor disposed within a housing of the motor drive system. The at least one sensor is configured to detect a current of output power produced by the motor drive system. The motor drive system also includes a controller configured to determine a resonant frequency of a cable connected to the motor drive system based at least in part on the detected current, and to adjust pulse width modulation (PWM) switching of the motor drive system based at least in part on the determined resonant frequency of the cable.
