The primary side power circuit includes a primary winding and a main switch coupled in series. The main switch is turned on and off in response to control signals. The secondary side power circuit includes a secondary winding, at least one synchronous rectifier switch, and an output inductor winding. The secondary winding is inductively coupled to the primary winding and forms a first magnetic coupling with the primary winding. The synchronous rectifier drive circuit includes a first and a second auxiliary winding coupled in series. The first auxiliary winding is inductively coupled to the primary winding and forms a second magnetic coupling with the primary winding. The second auxiliary winding is inductively coupled to the output inductor winding and forms a third magnetic coupling with the output inductor winding."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Drive circuit for synchronous rectifier and method thereof","description":"A power converter includes a primary side power circuit, a secondary side power circuit, and a synchronous rectifier drive circuit.
