Patent number: 9997903Abstract: A power supply device for plasma processing, wherein electric arcs may occur, comprises a power supply circuit for generating a voltage across output terminals, and a first switch connected between the power supply circuit and one of the output terminals. According to a first aspect the power supply device comprises a recovery energy circuit connected to the output terminals and to the power supply circuit. According to a second aspect the power supply device comprises an inductance circuit including an inductor and a second switch connected parallel to the inductor. According to a third aspect the power supply device comprises a controller for causing the power supply circuit and the first switch to be switched on and off. The controller is configured to determine a quenching time interval by means of a self-adaptive process. The quenching time interval defines the time interval during which, in an event of an arc, no voltage is generated across the output terminals.Type: GrantFiled: November 9, 2015Date of Patent: June 12, 2018Assignee: SOLVIX GMBHInventors: Albert Bulliard, Benoit Fragnière, Joël Oehen
