Patent number: 8482205Abstract: Operation of a plasma supply device having at least one switching bridge with at least two switching elements, and configured to deliver a high frequency output signal having a power of >500 W and a substantially constant fundamental frequency >3 MHz to a plasma load is accomplished by determining at least one operating parameter, at least one environmental parameter of at least one switching element and/or a switching bridge parameter, determining individual drive signals for the switching elements taking into account the at least one operating parameter, the at least one environmental parameter and/or the switching bridge parameter, and individually driving the switching elements with a respective drive signal.Type: GrantFiled: January 14, 2010Date of Patent: July 9, 2013Assignee: HUETTINGER Elektronik GmbH + Co. KGInventors: Thomas Kirchmeier, Michael Glueck, Hans-Juergen Windisch, Hanns-Joachim Knaus

Patent number: 8357874Abstract: A plasma supply device includes a full bridge circuit that is connected to a DC power supply and that has two half bridges each with two series connected switching elements. The plasma supply device further includes a primary winding of a power transformer connected to centers of the half bridges between the switching elements. The primary winding includes a tapping connectable to an alternating current center between the potentials of the DC power supply.Type: GrantFiled: July 23, 2008Date of Patent: January 22, 2013Assignee: Huettinger Elektronik GmbH + Co. KGInventors: Thomas Kirchmeier, Hans-Juergen Windisch, Hanns-Joachim Knaus, Michael Glueck

Patent number: 8222885Abstract: A high frequency power supply, in particular a plasma supply device, for generating an output power greater than 1 kW at a basic frequency of at least 3 MHz with at least one switch bridge, which has two series connected switching elements, wherein one of the switching elements is connected to a reference potential varying in operation, and is activated by a driver, and wherein the driver has a differential input with two signal inputs and is connected to the reference potential varying in operation.Type: GrantFiled: July 22, 2008Date of Patent: July 17, 2012Assignee: Huettinger Elektronik GmbH + Co. KGInventors: Thomas Kirchmeier, Hans-Juergen Windisch, Michael Glueck, Erich Pivit

Patent number: 8129653Abstract: A plasma supply device generates an output power greater than 500 W at an essentially constant basic frequency greater than 3 MHz and powers a plasma process to which is supplied the generated output power, and from which reflected power is returned to the plasma supply device. The plasma supply device includes at least one inverter connected to a DC power supply, which inverter has at least one switching element, and an output network. The output network is arranged on a printed circuit board. The output network can therefore be designed low priced and accurately.Type: GrantFiled: July 2, 2008Date of Patent: March 6, 2012Assignee: HUETTINGER Elektronik GmbH + Co.
