| 摘要 |
The invention relates to a plasma generating device characterised in that it comprises: a supply circuit (2) including a switch (M) controlled by a control signal (V1) for applying an intermediate voltage (Vinter) on an output of the control circuit at a frequency defined by the control signal; a plurality of plasma-generating plug coils (BB1, BB2, BB3, BB4) arranged in parallel on said output via connectors (20), each connector being adapted to be removably connected to a corresponding plug coil and including means (23) adapted for offsetting the resonance frequency of said plug coil so that each plug coil has a distinct resonance frequency; a control device (5) of the supply circuit, that determines the control frequency from the resonance frequencies of the plug coils in order to selectively control the plug coils according to the control frequency used.
