Definitions

  • a change of the frequency of the control signal V1 corresponding to a jump of frequency of the initial frequency f 0 to a frequency f 1 , -chosen, as explained above, in a frequency range between f 0 and f 0 - ( ⁇ f / 2).
  • the new control frequency value f 1 is for example chosen between f 0 and f 0 - 100 kHz.
  • the figure 2b using the same chronograms as the figure 2a , then illustrates the case provided by the present invention, wherein the modification of the frequency of the excitation signal V2 is advantageously performed synchronously with the time t b of switching of the control signal V1 to the new control frequency f 1 . .
  • Such synchronous frequency control of the resonator makes it possible to maintain the maximum quality factor of the radiofrequency candle, whatever the mode of its operation and thus to preserve the characteristics of the spark.
  • any frequency change of the excitation signal of the resonator of the RF candle must be synchronous with the control signal.
  • the switching time t b through which the control signal V1 passes before application of the new control frequency, must preferably be controlled to be substantially equal to the duration of a half-period of the control signal. before application of the change of frequency.
  • the figure 4 illustrates an exemplary embodiment of frequency control means according to the invention of the control module providing the control signal V1 of the radio frequency power supply.
  • These control means are therefore adapted to shift the frequency of the control signal of the power supply, from an initial control frequency to a new control frequency, so that the frequency change of the excitation signal of the resonator which in turn flows either synchronized with the control signal. In this way, the control signal remains in phase with the oscillations of the excitation signal of the resonator, throughout the application of the excitation signal.
  • control means comprises a voltage controlled oscillator VCO 40, the output of which is connected to the control module 30 to supply the control signal V1, and a control input 41 of which is connected to a control voltage source 50, adapted to drive the VCO by a modulation of the control voltage own to control a change in the frequency of the control signal provided on the gate of transistor M.
  • optimizing the development of the spark of the radiofrequency candle requires that it be possible to make up part of the disagreement of the power supply system by controlling a frequency change in real time within a train of excitement of the candle, respecting the synchronization condition of this change with the control signal.
  • the modification of the excitation frequency of the resonant system must be synchronized, according to the preceding description in relation with the application of automobile ignition to plasma generation, the time t b of switching of the control signal to a new control frequency value, defining the new excitation frequency.
  • the new excitation frequency must also be between f 0 and f 0 +/- ( ⁇ f / 2) (depending on whether the resonant frequency has increased or decreased), ⁇ f corresponding to the bandwidth of the resonant system.
  • the resonance frequency change of the resonant system can be detected in real time by measuring a characteristic magnitude of the resonant system, such as the quality factor.
  • the modification of the excitation frequency of the system should preferably be made as soon as a variation of the resonance frequency greater than 10% of the bandwidth ⁇ f is detected.
