Abstract
A flyback converter can include: a power switch controlled to be turned on/off to control a current through a primary side; a first primary winding coupled between an input terminal and a first terminal of the power switch, where a dotted terminal of the first primary winding is coupled to a first terminal of the power switch; a second primary winding coupled between a second terminal of the power switch and a primary grounding terminal, where a dotted terminal of the second primary winding is coupled to the primary grounding terminal; a secondary winding configured between the first and second primary windings in a radial direction of a magnetic core, where the first primary winding, the second primary winding, and the secondary winding are wound around the magnetic core; and a secondary rectifier and filter circuit coupled with the secondary winding, and configured to generate a stable current/voltage.
