Abstract
A multi-port electromagnetic device comprises a first magnetic core having a first closed flux path and a second magnetic core having a second closed flux path, with the first closed flux path being independent from the second closed flux path. At least one first winding electromagnetically couples the first magnetic core to the second magnetic core, and at least one second winding electromagnetically couples the first magnetic core to the second magnetic core independent of the electromagnetic coupling of the at least one first winding such that current application in one of the first or second windings does not induce a magnetic flux in the other one of the first or second windings.

A multi-port electromagnetic device, comprising:
- a first magnetic core having a first closed flux path;
- a second magnetic core having a second closed flux path, said first closed flux path being independent from the second closed flux path;
- at least one first winding that electromagnetically couples the first magnetic core to the second magnetic core;
- at least one second winding that electromagnetically couples the first magnetic core to the second magnetic core independent of the electromagnetic coupling of the at least one first winding such that current application in one of the first or second windings does not induce a magnetic flux in the other one of the first or second windings.
An electromagnetic device, comprising:
- a first magnetic core having a first closed magnetic flux path;
- a second magnetic core having a second closed magnetic flux path, said first closed magnetic flux path being decoupled from the second closed magnetic flux path;
- a first inductor comprising a first winding that electromagnetically couples the first magnetic core to the second magnetic core;
- and
- a second inductor that is electromagnetically independent of the first inductor comprising a second winding that electromagnetically couples the first magnetic core to the second magnetic core.
