Abstract:
1. A method for compensating tolerances of electrical components of an inductive coupler, comprising: generating a first sequence of at least one pulse of a direct-current voltage or at least one period of an alternating-current voltage into a resonance circuit of the inductive coupler; short-circuiting the resonance circuit subsequent to generating the first sequence to cause the resonance circuit to oscillate at a first resonance frequency; measuring the first resonance frequency; generating a second sequence having a plurality of pulses of a direct-current voltage or a plurality of periods of an alternating-current voltage so that a given voltage is built-up on a charging capacitor of the inductive coupler; short-circuiting the resonance circuit subsequent to generating the second sequence to cause the resonance circuit to oscillate at a second resonance frequency; measuring the second resonance frequency; and determining, from the measured first and second resonance frequencies, at least one value of a parameter which affects operation of a power generator of the inductive coupler.
