Optimum control of the resonant frequency of a resonator in a radiofrequency ignition system

摘要

A supply device for a radio frequency ignition system, including a supply circuit to provide a supply voltage to an output connected to a plasma generation resonator at a frequency defined by a control signal provided by a control device for the supply circuit. The control device includes a receiver interface for a determination request for the optimum control frequency, a receiver interface for receiving signals measuring the voltage at the pins of a capacitor in the supply circuit, a determination module for the optimum control frequency, to provide successive different control frequencies for the supply circuit for successive ignition commands on reception of a request and to determine an optimum control frequency based on received measured signals.
