Method for compensating for system tolerances in inductive couplers

The method involves generating a short sequence of pulse of direct voltage, and short-circuiting a series-resonant circuit. Frequency of oscillation generated in the resonant circuit is measured, and a long sequence of more pulses of direct voltage is generated. Another frequency of the oscillation generated in the resonant circuit, and a control parameter for controlling a power generator (50) is determined based on value tables of the frequencies. An error signal is provided when the former frequency and/or the latter frequency lies outside of a predetermined value margin. Independent claims are also included for the following: (1) an inductive coupling device with a control device for executing a method for compensating system tolerances (2) a computer tomograph comprising an inductive coupling device.
