  • Patent number: 8025775
    Abstract: A vacuum plasma generator with an output for feeding a plasma discharge for treatment of workpieces in a vacuum chamber has a connection for the junction to AC voltage mains, a rectifier connected to a converter with a control input for the setting and/or regulation of the converter output voltage, and a controlled full bridge circuit connected to the converter output with a potential-free generator output, which transposes the converter output voltage into pulses of 1 to 500 kHz. A potential-isolating transformer is switched into the bridge for the galvanic decoupling of the generator output.

  • Patent number: 7455755
    Abstract: The invention relates to a vacuum plasma generator for providing a plasma discharge (10) for treating work pieces (5) by way of a pulsed plasma process in a vacuum chamber (2). Said vacuum plasma generator comprises a generator output (9, 9?) having an AC mains supply (6a), an AC/DC mains rectifier system (6) for rectifying the AC mains voltage to a DC voltage, a filter capacitor (6b), a first stage as clocked DC/DC voltage converter (7) with means for adjusting the DC output voltage which produces an intermediate circuit voltage (Uz), comprising a controlled power switch (7a) which feeds the primary winding of a transformer (14) and the secondary winding of which is connected to a rectifier (15) and a downstream intermediate capacitor (12) and configures a floating transformer secondary circuit (23). Said secondary circuit is connected to a downstream second stage which is a pulse output stage (8) and is connected to the generator output (9, 9?).
