SYSTEM AND METHOD TO AVOID MAGNETIC POWER LOSS WHILE PROVIDING ALTERNATING CURRENT THROUGH A FERROMAGNETIC MATERIAL

摘要

This disclosure provides systems, methods and apparatus for avoiding magnetic power loss while providing alternating current through a ferromagnetic material. In one aspect, the ferromagnetic material includes at least one orifice. At least one electrical conduit extends through the at least one orifice from a first region on a first side of the ferromagnetic material to a second region on a second side of the ferromagnetic material, the second side opposite to the first side. The at least one electrical conduit is configured to have at least one alternating current flowing along the at least one electrical conduit between the first region and the second region. The ferromagnetic material and the at least one electrical conduit are configured to reduce power loss caused by a circumferential magnetic flux generated within the ferromagnetic material by the at least one alternating current.
