Claim:
1. A corona ignition system for igniting fuel in a combustion chamber of an internal combustion engine, comprising: an oscillating circuit containing an ignition electrode; a high-frequency generator connected to the oscillating circuit and configured to produce an AC voltage for exciting the oscillating circuit; a converter configured to produce an input voltage for the high-frequency generator; a voltage controller configured to stabilize the input voltage produced by the converter for the high-frequency generator at a target value; a control unit configured for controlling the high-frequency generator; wherein the control unit is configured to communicate an imminent load change of the converter to the voltage controller, before the load change resulting from activation or deactivation of the high-frequency generator occurs; and wherein the voltage controller is configured to respond to a communication of the control unit concerning an imminent load change by changing the target value to a changed target value and the converter begins producing the input voltage for the high-frequency generator at the changed target value before occurrence of the imminent load change.
