Abstract
Dividing a single phase PWM signal into a plurality of phases includes: receiving, from a phase controller by a PWM frequency divider, an input pulse train comprising a period; and dividing, by the PWM frequency divider, the input pulse train amongst a plurality of output phases of the PWM frequency divider, including, at the onset of each period of the input pulse train: providing, on a next output phase of the PWM frequency divider, an output pulse train; and holding all other output phases at a tri-state voltage level.
