Abstract (en)
The plug has a series resonator with a resonance frequency higher than 1MHz and having a capacitor (111) whose terminals are connected to two electrodes (103, 106) for plasma generation. One electrode forms a spark plug shell and another electrode behaves as an anode. A radiofrequency excitation is applied to the plug and an insulating sleeve (100) separates free ends of the electrodes. Independent claims are also included for the following: (a) a plasma generation system including a spark plug; and (b) a plasma generation method.
Abstract (fr)
L'invention propose un système de génération de plasma(1), comprenant: - deux électrodes (103, 106); - un matériau diélectrique (100) séparant les électrodes; - un générateur de tension (102), connecté aux électrodes appliquant sélectivement une tension alternative présentant une fréquence supérieure à 1 MHz et une amplitude entre crêtes supérieure à 5kV entre les électrodes. L'invention porte aussi sur un procédé associé et permet notamment de générer aisément un plasma de volume ou un plasma ramifié.
