Abstract
An induction energy transfer device comprises a static power conversion circuit for producing an alternating magnetic field of ultrasonic frequency. The static power conversion circuit includes a parallel resonant circuit which comprises a coil which also couples power across an air gap. An improvement in efficiency and power transfer is obtained by including at least two such parallel resonant circuits in the power conversion circuit. One of the resonant circuits is tuned to the third harmonic of the fundamental frequency. The open magnetic field can serve for the inductive transmission of electrical energy from a circuit-containing primary apparatus over a distance to a matching equipped secondary apparatus.
