Abstract
A system for wireless power transfer having a power transfer device, including a capacitor unit and an inductor unit connected in series to form an LC resonant circuit. The inductor unit is designed to form an envelope with a toroidal shape, the envelope forming an inductor coil with at least one turn, which generates an oscillating magnetic field outside of the envelope used for the wireless power transfer. The ends of each turn are electrically insulated from each other by means of an insulation gap, and appropriately connected by wires inside the envelope. The capacitor unit is disposed inside this envelope such that the envelope wraps the capacitor unit and wires between the capacitor unit and the inductor unit.
