Abstract
A converter circuit includes an input filter including an input capacitor configured to filter electromagnetic interference from an input voltage. The converter circuit includes an output capacitor, a first inductor coupled to the input capacitor, a switch coupled to the first inductor and configured to control a level of current flowing in the first inductor, a coupling capacitor connected to the first inductor, and an output rectifier coupled between the coupling capacitor and the output capacitor. A damping circuit that is configured to damp a resonant frequency of the converter circuit is coupled in parallel with the coupling capacitor.
