SKYPER® Prime Family – Drives up to 1400A and 1700V

Plug & Play driver with integrated and galvanically insulated sense signals for SEMITRANS 10 and PrimePack modules with optical or electrical interface.

SKYPER® Prime Benefits

Regenerative converters are driven by two main market requirements. Increasing the output power and reduction of cost. SKYPER Prime offers galvanically insulated and very accurate sensor signals. Thus, the customer saves the cost of external power supplies, external sensing circuits and their insulation. The sensor data is available as digital signals which can be directly fed to the customer’s controller. A / D conversions or level adjustments, which reduce the accuracy, are omitted. Thanks to this high accuracy, the customer can go to the limits of the IGBT modules.

SKYPER Prime is a fully qualified Plug and Play driver with optimised SOA characteristics. This saves costly qualification and redesign loops and at the same time offers significant performance advantages. The new SEMIKRON ASIC chipset allows for maximum integration and thus a very high reliability rate: MTBF >5million hours at full load.

To maximise the performance, a new concept has been developed for paralleling the drivers. Very accurate switching behaviour with digital signal processing, parallel fault management and symmetric signal paralleling provide maximum output power. As a new version, an optical interface is available. Additional to the switching and error signals, the temperature and DC link signals are transmitted directly to the control unit. Electrical and optical versions are available as coated types for tough applications.

SKYPER® Prime Key Features

  • Insulated DC link signal
  • Insulated temperature signal
  • Digital sensor signals for direct connection to the μC
  • Fast Vce detection
  • SoftOff with separated output stage
  • UL recognised, safe electrical insulation
  • ROHS compliant
  • Stabilised positive and negative gate voltages
  • Qualified SOA of driver + IGBT module
  • Paralleling with accurate switching
  • Internal dead time generation
  • Double side under-voltage protection

SKYPER® Prime Applications

SKYPER Prime can drive IGBTs up to 1400A and 1700V. Thanks to its built-in sensor signal processing and the paralleling concept SKYPER Prime provides the optimum IGBT driver solution for high performance applications up to the megawatt range. Applications benefiting most from that performance and from the long service life are large power supplies and regenerative inverters. The  qualification level and the coating option allow the direct use in traction applications.
