Method and apparatus for power converter input voltage regulation

摘要

A method and apparatus for regulating an input voltage to a power conversion module. In one embodiment, the method comprises computing a voltage regulation threshold based on an output voltage for the power conversion module; comparing an input voltage of the power conversion module to the voltage regulation threshold; and generating, when the input voltage satisfies the voltage regulation threshold, an average input voltage less than the voltage regulation threshold, wherein the average input voltage is generated from the input voltage.
