SKiiP® Benefits

SKiiP4 is the most powerful IPM on the market. SKiiP4 modules enable the production of converter units with outputs of up to 2.1MW. The power semiconductors used in SKiiP4 modules can be operated at a junction temperature of up to 175°C. To make sure these components can be reliably used at these temperatures, the power circuitry is 100% solder-free. Sinter technology is used to create a sintered silver layer instead of the solder layer which could limit the service life of power modules. Reliability during active and passive thermal cycling is greatly improved. A further benefit is the better load cycling capability as compared to solder-based modules.

The integrated gate driver in the SKiiP4 sets new standards in terms of reliability and functionality. The digital driver guarantees safe isolation between the primary and secondary side, both for switching signals and all measurement parameters, such as temperature and DC link voltage. This means the user no longer has to introduce complex and costly circuit components to provide safe isolation. For the first time, the SKiiP drive features a CANopen diagnosis channel for the integration of additional functions.

SKiiP® Key Features


  • DC-Link monitoring (SKiiP3, SKiiP4)
  • Current sensors (SKiiP3, SKiiP4)
  • Temperature measurement (SKiiP3, SKiiP4)
  • CAN diagnostic interface (SKiiP4)
  • 100% solder-free (SKiiP4)
  • Water, air and customized cooler

Production and Test

  • 100% tested (function, isolation, protection function)
  • Burn-In (SKiiP3 on request, SKiiP4 = 100%)

SKiiP® Applications

The success story of the SKiiP family has progressed hand in hand with the advancement of the wind power market. The 4th generation SKiiP modules are a further improvement of the powerful SKiiP series. The mainstay of SKiiP4 modules is the wind power sector, with approximately 57GW out of the 122GW of wind power installed worldwide (at the end of 2009) featuring SEMIKRON solutions, in many cases SKiiP technology. Besides wind power applications, SKiiP modules can also be found in elevators, solar power and railway applications – in fact, in any area where powerful, safe and reliable IGBT IPMs are a must.

SKiiP® Product Range

SKiiP4 is available for 1200V and 1700V. In both of these voltage classes, SKiiP4 modules come in the topologies 3GB 1800A, 4GB 2400A and – new to the SKiiP family – 6GB 3600A. The wide range of accessories is now available for both SKiiP3 and SKiiP4. Among them the fiber optic boards, the boards for paralleling of SKiiP systems and the adapter board for connection of SKiiP4 to SKiiP3 controller.
