摘要：A power supply circuit includes: an anti-electromagnetic interference circuitconfigured to receive input alternating current power and to output filtered alternating

current power; a rectifier circuit configured to rectify the filtered alternating currentpower; a current correction circuit configured to perform passive power factor correctionon the rectified alternating current power; a single-ended flyback converter circuitcoupled to the output of the current correction circuit; and a dimming control circuitcoupled between the output of the single-ended flyback converter circuit and a lightload, wherein the current correction circuit is configured to control a waveform of therectified alternating current power to follow a current output to the light load in orderto provide passive power factor correction.
