Power converter with primary-side feedback control

Abstract

A power converter with primary-side feedback control includes a transformer comprising a primary winding, an auxiliary winding, and a secondary winding, for transforming an input voltage into an output voltage; a transistor coupled to the primary winding for controlling electric energy transforming of the transformer according to a first control signal; a control unit coupled to the transistor for generating the first control signal according to a feedback signal in order to control the transistor to be turned on or off; and a peak detection unit coupled between the auxiliary winding and the control unit for generating the feedback signal according to a knee voltage of a first voltage signal.
