Abstract :
A common mode EMI reduction technique of a flyback converter using a wire shield is presented. The capacitance model of the flyback transformer is derived and it is used to determine the values of the wire shield turns and compensation capacitor minimizing the noise voltage. The experimental results for an actual adaptor are provided to verify the effectiveness of the proposed method.
