Unipolar Pulsed DC Power Supply


The PLASMATEC DCp, the unipolar pulsed DC power supply from the proven J. Schneider PLASMATEC power supply platform for PVD, is a switched-mode power supply with the state of the art CFC (Current Fed Converter) technology. By the use of the CFC technology the output of the power supply is a true current source, the most sophisticated solution for defect free plasma processing. The PLASMATEC DCp delivers DC or unipolar pulsed DC at an output frequency of 76kHz. The power supply is available with 5kW, 10kW or 20kW. The systems can be put in parallel mode to increase the power up to 160kW. The regulation of current, voltage and power reach most accurate values via digital regulation. The PLASMATEC DCp is characterized by a high power density and great robustness. Extremely low stored output energy and a sophisticated, flexible, adjustable arc management. It is ideal for industrial applications as well as for research equipment for surface developments. Its main applications are in vacuum coating processes for hard/decorative, tribological and functional coatings, optical glasses, solar cells, architecture glasses or for flat screens.

  • Optimized for defect-free processing, for state of the art thin film technologies
  • Small footprint, up to 20kW in 3HU
  • Extremely low internal stored energy (<3mJ / 10kW)
  • Water cooled
