Abstract:
The present invention discloses a full-range-duty PWM signal generation method for an AC-to-DC power conversion, comprising the steps of: generating a saw-tooth signal with a predetermined valley voltage; generating a reference signal according to at least one of a current feedback signal and a voltage feedback signal; and generating a PWM signal according to voltage comparison of the saw-tooth signal and the reference signal. Furthermore, the present invention also provides a full-range-duty PWM signal generation apparatus for an AC-to-DC power conversion, and a system using the full-range-duty PWM signal generation apparatus.
