Abstract
An AC/DC converter includes a rectifier circuit and an active power factor correction circuit. The rectifier circuit is electrically connected to a power supply, and is used to convert an alternate current into a direct current, wherein the rectifier circuit has a positive output and a negative output for sending out the direct current. The active power factor correction circuit electrically connects the rectifier circuit and a loading, wherein the active power factor correction circuit is used to suppress voltage ripples provided to the loading.
