Abstract:
A PWM control system includes a multi-phase PWM controller and at least one single-phase PWM controller. The multi-phase PWM controller is capable of generating a multi-phase PWM signal. The at least one single-phase PWM controller is capable of generating a single-phase PWM signal. A phase difference between the single-phase PWM signal and the multi-phase signal is greater than 0 degree and less than 180 degree.
