Abstract
Provided are a power supply apparatus, and a charging method and system. The apparatus includes: a rectifier module () configured to rectify an alternating current (alternating current) voltage to obtain a first pulsating direct current (direct current) voltage; a conversion module () configured to convert the first pulsating direct current voltage to obtain a stable direct current voltage; and a valley-fill circuit () having an input terminal connected to an output terminal of the rectifier module () and an output terminal connected to an input terminal of the conversion module (). The valley-fill circuit () is configured to release electric energy to the conversion module () when a voltage value of the first pulsating direct current voltage is smaller than a first voltage threshold, to increase a valley voltage of the first pulsating direct current voltage inputted to the conversion module ().
