  • Control of a plurality of plug coils via a single power stage
    Patent number: 8547020
    Abstract: A radiofrequency plasma generating device including: a supply circuit including a switch controlled by a control signal for applying a voltage on an output of the control circuit at a control frequency; at least two plasma-generating circuits connected in parallel at the output of the supply circuits, each circuit having its own resonance frequency and being capable of generating plasma when a high voltage level is applied to the output of the supply circuit at a frequency substantially equal to the resonance frequency of the plasma generation circuit; and a supply control device determining the control frequency from the resonance frequencies of the plasma generation circuits to selectively control each circuit according to the control frequency used.
    Type: Grant
