Inductive Coupling through a Steel Enclosure

Ms.Malamu Habavir · 2006-11-22T10:51:02+00:00

I am trying to inductively-couple, for the purpose of charging a battery (capacitor bank), across a 5mm space. On each side of the gap is mild steel channel stock of approximately 10mm thick. The inductive coupling frequency is around 1 MHz. While the coupling works on the bench, the steel greatly affects the field. Is there any technique for lessening the affects? Any links or hints would be greatly appreciated.Thanks.

If holes are being cut in the steel for cores, can you pass light between the two boxes? Like a bright globe or LED and a solar panel on the other side, this will give you a few watts out of 100.

I once made a battery charger that would charge across an airgap of around 3cm using resonant LC on each end. Not particularly high power, but not wildly inefficient either.
