Abstract

Disclosed are a rectifying circuit and a switched-mode power supply. The rectifying circuit includes a first rectifying section for rectifying a positive induced voltage generated across a secondary winding of a transformer, a second rectifying section for rectifying a negative induced voltage generated across the secondary winding, and an inductance section connected between the first rectifying section and the second rectifying section. The switched-mode power supply includes a transformer having a primary winding and a secondary winding, a drive circuit for switchingly driving the primary winding of the transformer, and the rectifying circuit connected to the secondary winding of the transformer.
