Inverter platform for renewable energy applications

The Semistack for renewable energy comprises three modular half-bridge phase cells

Hertford based Semikron has introduced an inverter platform designed to offer system integrators an easy to use and versatile inverter to meet the stringent demands of the renewable energy market.

The Semistack assembly is a high power, three phase inverter system that uses Semikron's SKiiP intelligent power module with integrated heat sink, IGBT, driver with protective sensors and functions, all optimised for renewable energy applications. The modular topology, the wide selection of SKiiP IPM power ratings, choice of cooling system and the ability to connect the inverters in parallel allows for a wide range of user applications from around 450kW to more than 3MW.

The base inverter configuration comprises three half bridge phase cells mechanically arranged in a vertical configuration. Each phase cell contains one SKiiP IPM, cooling system, polypropylene dc link capacitors, ac connections and snubbers.

The functional design of the Semistack for renewable energy allows assemblies to be easily connected together at the dc link with a low inductance bus coupling connected between stacks. This, says Semikron, makes it easy to configure four quadrant applications and to parallel the inverters for higher power. Moreover, a brake chopper can be added by using another Semistack assembly. This flexibility enables the systems integrator to easily build a range of different power ratings using the same components.

Semistacks for renewable applications undergo rigorous qualification processes in accordance with a combination of international and in house standards, including electrical, thermal, thermal cycling, environmental and shock & vibration.
