Active Pulsed DC Power Supply


The PLASMATEC Ap, 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 Ap alternatively provides a DC or unipolar pulsed DC current / voltage at an output frequency of 76 kHz. Unique for this PLASMATEC Ap unit is the optional and fully active adjustable reverse pulse mode with Arc detection.

The power supply is available with 5 kW and 10 kW. The 10 kW can be put in parallel mode to increase the power up to 80 kW. The regulation of current, voltage and power reaches most accurate values via digital regulation. The PLASMATEC Ap is characterized by a high power density and great robustness and 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 10 kW in 3 HU within active adjustable reverse pulsing
  • Extremely low internal stored energy (<3 mJ / 10 kW)
  • Water cooled
