PLASMA IGNITION SYSTEM AND METHOD FOR THE OPERATION THEREOF

摘要

The invention relates to a plasma ignition system comprising a resonator (15) for generating a high-frequency voltage on electrodes in a combustion chamber; a high-frequency voltage source (12) for generating a burst signal (8) that can be supplied to the resonator, for the production of a plasma (6) having an output impedance which is adapted to the input impedance of the resonator before the ignition of a plasma; a high-frequency voltage source (13) for generating a supply signal (9) which can be supplied to the resonator (15) in order to maintain the plasma (6), the output impedance of the voltage source being approximately equal to the impedance of the resonator when the plasma is present with optimum expansion and power absorbency; a frequency diplexer (14) for the separation of the voltage source (12) and the high-frequency voltage source (13) on the output side; and a control/regulating unit (10) for the relative temporal control of the burst signal (8) and the supply signal (9).
