Abstract
The present disclosure provides a dynamic pulse width modulation (PWM) system that includes current frequency determination circuitry to determine a DC value of a source current, and to determine a frequency of the source current generate a plurality of pulses from an AC power source; and PWM generation circuitry to generate a first PWM signal having a first frequency based on the DC value of the current source; the PWM circuitry also to generate a second PWM signal having a second frequency based on the frequency of the current source; wherein the first frequency is less than the second frequency.
