Abstract

A method for compensation of input voltage fluctuations in an inductive rotating coupler is disclosed. This coupler includes a power generator that feeds an alternating-current voltage into a resonance circuit including a resonance capacitor and an inductive rotating transmission device. The power generator is fed with an input direct-current voltage that may fluctuate, for example, owing to residual ripple. A control unit determines this input direct-current voltage and calculates there from an optimum operating frequency for the power generator, so that the output voltage at the load remains constant.
