Patent number: 8653405Abstract: In one aspect, operating a vacuum plasma process system including a plasma discharge chamber is accomplished by generating a main plasma in the discharge chamber in a first operating state, and generating an auxiliary plasma in the discharge chamber in a second operating state. Generating the main plasma includes generating a main plasma power with a first number of RF power generators, and generating an auxiliary plasma power with a second number of RF power generators, such that the second number is smaller than the first number.Type: GrantFiled: November 13, 2006Date of Patent: February 18, 2014Assignee: HUETTINGER Elektronik GmbH + Co.

Patent number: 7745955Abstract: The power output of an RF plasma supply device is controlled by producing at least a first and second RF power signal by means of a respective RF generator, coupling at least two RF power signals into a coupled RF power, and distributing the coupled RF power between a plasma power that is to be supplied to a plasma load and an equalizing power that is to be supplied to an equalizing load. The power output is controlled by adjusting the levels and/or the phase position of the RF power signals in such a manner that, for plasma power in the range between a predefined lower power limit and a predefined nominal power, an insignificant portion of the coupled RF power constitutes the equalizing power and, for plasma power below the predefined lower power limit, a significant portion of the coupled RF power constitutes the equalizing power.Type: GrantFiled: October 16, 2006Date of Patent: June 29, 2010Assignee: HUETTINGER Elektronik GmbH + Co.

Patent number: 6288553Abstract: The invention relates to a method for determining the loop resistance of a power supply network with a neutral conductor (called N), a phase or external conductor (called L1), a ground or protective earth conductor (called PE), and a fault current breaker (called FI) based on the differential quotient Ri=dU/dI≈(U1−U2)/(I1−I2); whereby U1 is the measured, unloaded network voltage, I1 is the zero current without load, U2 is the measured, loaded network voltage, and I2 is the calculated load current. According to one aspect of the invention, the following steps are provided: Loading of a L1-N loop and determining the resistance RL1 according to equation (1), loading of a N-PE loop with a measuring current IM under a measuring voltage UM which is small enough to avoid triggering of the fault current circuit breaker, and determining the resistance RPE according to the following equation (2): RPE=UM/IM (2) and determining the loop resistance as RL1+RPE.Type: GrantFiled: October 14, 1998Date of Patent: September 11, 2001Assignee: Ch.
