ABSTRACT:
In a power converter having a power train that includes a power switch and a rectifier for conducting forward currents from the power switch, a circuit for, and method of, reducing switching losses associated with the power train. The circuit includes: (1) an auxiliary switch and an inductor coupled to the power train that reduce a switching loss associated with the power switch and (2) an impedance element series-coupled to the rectifier that reduces a change in current through the rectifier thereby decreasing a reverse recovery current flowing therethrough.
