Abstract
A flyback converter with primary side and secondary side feedback control includes a transformer, a secondary-side feedback unit and a feedback control unit. The secondary-side feedback unit is electrically connected to a secondary winding of the transformer and comprises an isolated signal transceiver device and an error amplifier. The feedback control unit is electrically connected to an auxiliary winding of the transformer and operatively connected to the isolated signal transceiver device. When the flyback converter is operated in heavy load conditions, the feedback control unit receives a secondary feedback control signal sent from the isolated signal transceiver device for feedback control. When the flyback converter is operated in light load conditions, the feedback control unit receives a primary feedback control signal sensed by the auxiliary winding for feedback control.
