ABSTRACT:
An integrated structure of common-mode inductors and differential-mode capacitors in an EMI filter realized using a flexible circuit board, including: a closed magnetic circuit formed by a first magnetic core and a second magnetic core, optionally including an air gap formed in a middle pillar of the magnetic cores, and with a flexible printed circuit board (FPC) wound on at least one pillar, the FPC formed by laminating alternating insulating and copper foil layers. The integrated structure of inductors and capacitors is advantageous in reducing the volume of the EMI filter and improving the power density of an electronic power transformer.
