SKiiP® Benefits

The SKiiP IPM product line sets a benchmark for high performance and robust inverter designs. Both SKiiP 3 and SKiiP 4 feature high power densities combined with flexible cooling options, such as air and liquid cooling along with customized heat sinks. Reliable driver technology, integrated current sensors and comprehensive protection functions complete the IPM design.

SKiiP 3 is widely proliferated in the industrial drive segment. With its sixpack and half-bridge topologies, it covers a current range from 500A up to 2400A.

The SKiiP 4 is available in half-bridge topology, it has been optimized for highest power cycling requirements and covers the higher power range up to 3600A. It is the most powerful Intelligent Power Modules on the market.

SKiiP 4 increases reliability for demanding power cycling conditions thanks to silver sintering and High-Performance Cooler Technology. Extend operation lifetime with Sinter Technology, increases resilience to active and passive thermal cycling compared to a conventional solder approach. SKiiP 4 digital drivers reduce design complexity and costly components and provide safe isolation for both switching signals and parameter measurement. In addition to a high reliability design, SKiiP 4 drivers also include CAN-bus functionality.

SKiiP® Short Facts

SKiiP® Applications

SKiiP fully meets the specific requirements for wind turbines up to the 3MW power range and can be easily paralleled to achieve more power. In addition to wind power applications, SKiiP modules are also in elevators, solar inverters and railway applications – in fact, in any area where powerful, safe and reliable IGBT IPMs are needed.

SKiiP® Product Range

SKiiP IPMs are available in half-bridge and sixpack topologies with power ratings up to 3MW without paralleling. In addition to air- and liquid-cooling, customised cooling is also available in SKiiP 3 and SKiiP 4. accessories for interfacing SKiiP 3 and SKiiP 4 to control boards are also available, including fibre-optic, paralleling and adapter boards.

SKiiP® 4 on Double Sided HPC

The new High-Performance Cooler (HPC) can also be used with double side mounted SKiiP4. This allows maximum of power density without any loss of performance. You can operate these two SKiiP4 IPMs individually, for example for grid and machine side of an active frontend converter, or parallel them to double the output power.

Individual settings for installed diodes and IGBT power are available for grid and machine side SKiiP 4 IPMs.
