Design approach for EMI filters in power supplies

A new design approach is introduced aimed at reducing the size of electromagnetic interference (EMI) filters in power supplies. This method is based on the use of either embedded capacitors or new topologies, the latter limiting parasitic elements responsible for performance degradation. The efficie...

Summary:A new design approach is introduced aimed at reducing the size of electromagnetic interference (EMI) filters in power supplies. This method is based on the use of either embedded capacitors or new topologies, the latter limiting parasitic elements responsible for performance degradation. The efficiency of both methods is demonstrated by measurements.
