Abstract

A method is disclosed for compensation of system tolerances in an inductive coupler which includes a power generator that feeds an alternating current into a series resonance circuit formed by a resonance capacitor and an inductive rotating transmission device. First, a brief sequence of at least one period of an alternating current is fed by the power generator into the series resonance circuit. Then the series resonance circuit is short-circuited. A first resonance frequency is measured. Then a longer sequence having a plurality of periods of an alternating-current voltage is generated by the power generator, so that a given small voltage is built up at the load. Now a second resonance frequency is measured while the resonance circuit is short-circuited. Then at least one correcting variable for the power generator is determined from the two resonance frequencies.
