Abstract

A power generator, including a transformer with a primary winding arrangement and a secondary winding arrangement which is inductively coupled thereto, the primary winding arrangement forming a resonant circuit in conjunction with a capacitor, and a load being connected to the secondary winding arrangement. Therein, one winding arrangement of the transformer forms part of a series resonant circuit and, the other winding arrangement forms part of a parallel resonant circuit, the resonance frequency of the series resonant circuit is lower than the resonance frequency of the parallel resonant circuit, and the primary winding is connected to an alternating voltage generator so that an essentially sinusoidal alternating current flows through the primary winding.
