A method for producing an arc detection signal on the basis of a plurality of observation signals comprises producing an arc detection part-signal for each of at least two observation signals. Producing each of the part-signals includes correlating the respective observation signal with a correlation signal by influencing the correlation signal with the respective observation, thereby producing a correlation result; producing or modifying a coefficient on the basis of the correlation result; and weighting the respective observation signal with the coefficient. The arc detection part-signals are added to form the arc detection signal.

Method for producing an arc detection signal and arc detection arrangement

An arc suppression arrangement suppresses arcs in a gas discharge device that is operated with an alternating voltage from a power supply. The arc suppression arrangement includes an arc suppression device and an arc identification device that controls the arc suppression device. The arc suppression device includes at least one controllable resistor that is connected in series in an electrical line that extends from an alternating voltage source to an electrode of the gas discharge device. An arc can thereby be prevented from being provided with energy.

An aircraft induction oven excitation arrangement includes at least one connection for an on-board power supply system, at least one power supply rectifier that can be connected to a phase of the power supply system, a converter that is arranged downstream of the at least one power supply rectifier and that includes a switching element, a controller that drives the at least one converter, a rectifier that is arranged downstream of the converter in order to produce an intermediate circuit voltage, an inverter that is connected to the intermediate circuit voltage. The switching element has a turn-on resistance R&#x2266;about 0.1&#x3a9; and a self-capacitance &#x2266;about 200 pF at voltages of &#x2267;about 200 V across the switching element.

An arc detection means for detecting arcs in a plasma process includes at least one comparator to which an evaluation signal such as an output signal or an internal signal of an AC generator relating to the output signal and a reference value are supplied. The comparator is connected to a logic component that generates a signal for an arc suppression device.

Method and device for detecting arcs

New methods are used for detecting arcs in a plasma process that is fed by, for example, a freely oscillating AC generator with an output signal of the AC generator for supplying power. The method includes measuring or determining a reference value that is based on a time response of the output signal or of an internal signal of the AC generator relating to the output signal. The methods also include comparing the reference value with a threshold value and detecting an arc when a predetermined result of the comparison is obtained.
