Abstract

A common-mode noise cancellation circuit includes a capacitor and an inductor. The inductor has a three coupled winding, including a first coupled winding, a second coupled winding, and a third coupled winding. An input end of the first coupled winding and an input end of the second coupled winding are respectively coupled to two ends of an input power source. An input end of the third coupled winding is coupled to the output end of the second coupled winding, and an output end of the third coupled winding is coupled to the capacitor. An output end of the first coupled winding and an output end of the second coupled winding are respectively coupled to two input ends of a power conversion stage.
