CORONA IGNITION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE AND METHOD FOR CONTROLLING A CORONA IGNITION SYSTEM

摘要

A corona ignition system for igniting fuel in a combustion chamber of an internal combustion engine, comprising a oscillating circuit, which contains an ignition electrode, a high-frequency generator, which is connected to the oscillating circuit, in order to produce an AC voltage to excite the oscillating circuit, a converter in order to produce an input voltage for the high-frequency generator from an on-board supply voltage, a voltage controller to stabilize the input voltage produced by the converter for the high-frequency generator, and a control unit for controlling the high-frequency generator, wherein the control unit communicates an imminent load change of the converter to the voltage regulator, before the load change occurs as a result of activation or deactivation of the high-frequency generator. A method for controlling a corona ignition system is also described.
