Abstract

A common-mode (CM) active filter was designed in a compact package to suppress CM conducted emission at a switching mode power supply. A very compact structure was implemented in the voltage-sense voltage-compensation feedforward topology. The proposed filter was analyzed, and a prototype was applied to a real switching mode power supply (SMPS) board, demonstrating its usefulness by experiments.
