Abstract
A rotating power transformer comprises a primary magnetic core with a primary winding and a secondary magnetic core with a secondary winding. The magnetic cores preferably comprise a ferrite material and are U-shaped, and have a base connecting two legs. The width of the legs is significantly larger than the height of the base, resulting in a better magnetic coupling and a significantly improved tolerance to mechanical deviations.
