Abstract :
Common mode (CM) electromagnetic interference in power lines are typically reduced with a CM filter, which consists of discrete capacitors and inductors. An air-cored EMI filter with CM choke and integrated X and Y capacitors utilizing the parasitic capacitance of the windings is proposed. Its benefits include better high frequency performance, reduced component count, and improved manufacturability. Experimental results are provided.
