Abstract
A common-mode choke includes a plurality of hybrid core inductors and a printed circuit board. Each of the plurality of hybrid core inductors includes a first core made of a first material, a second core made of a second material, and at least one common coil configured to generate a magnetic field in both the first and second cores. The printed circuit board is configured to connect the plurality of hybrid core inductors in series.

A power conversion system comprising:
- a three-phase input power source;
- an active rectifier that converts alternating current from the three-phase power source into direct current power for a load;
- at least one planar common-mode choke connected to filter common-mode electromagnetic interference generated by the active rectifier, wherein the at least one planar common-mode choke comprises:
- a plurality of hybrid core inductors that each comprise a first core and a second core, wherein the first core and the second core share at least one multiphase coil connected to the three-phase power source;
- and
- a printed circuit board configured to connect the plurality of hybrid core inductors in series, wherein the plurality of hybrid core inductors are connected to the printed circuit board in a planar configuration.
