Device and Method of Non-Contact Energy Transmission
First Claim
1. A transformer device comprising at least a primary side and at least a secondary side separate from the primary side, for transmission of electrical energy without electrical connection, where the primary winding of the transformer is connected in series with a capacitor, and where the capacitor, mainly together with the leakage inductance of the transformer, forms a resonant circuit, wherein the resonant circuit is connected to a frequency controllable current source.
