SEMIKUBE® Benefits

Extending the SEMIKUBE portfolio, the SEMIKUBE SlimLine platform is a family of pre-qualified power assemblies which follow the same rigorous SEMIKRON qualification and certifications. The platform integrates advanced technologies which maximize performance and power density. SEMIKUBE SlimLine platform has been designed to fit applications in severe environments. Suitable for outdoor cabinets, the platform can be placed in environments subject to high temperature fluctuations. Extremely slim, the platform can be mounted into 300mm deep cabinets.

SEMIKUBE, by its modular design and patented DC clamp, enables the construction of various converter topologies. The platform design facilitates easy arrangement in the cabinet owing to the separation of the main cooling air flow through the heatsink and its IP54 rated mounting flange. The new SEMIKUBE 1500V, with its state of the art driver, provides a fast and cost effective alternative to 3 level solutions.

SEMIKUBE® Applications

Following the philosophy of the SEMIKUBE, the SEMIKUBE SlimLine is optimised for solar PV central inverters. Sized for the most commonly used central inverter ratings on the market, i.e. 500kW, 670kW up to 900kW, the SEMIKUBE SlimLine 3-phase inverter operates up to 1000VDC bus voltage. Designed in accordance with IEC 62109, the platform is poised to obtain UL 1000V recognition. SEMIKUBE SlimLine complies with most AC drives application requirements. The current measurement precision of 1% (at 25°C) allows for premium motor control required for highly dynamic applications and motion control systems.

SEMIKUBE® Product Range

The SEMIKUBE offers four frame sizes of continuous rated current from 150A to 1500A, using SEMITRANS 1200V IGBT Trench E4 modules. SEMIKUBE SlimLine design is optimised for 3-phase inverter topologies. Dedicated rectifier with 3-phase inverter and optional brake chopper may be added.

The IGBTs are controlled by a SEMIKRON embedded driver, which provides error management, and analogue outputs of current, DC voltage and heatsink temperature. A CAN interface is available for parameter configuration and diagnostics monitoring. Air cooling for SEMIKUBE SlimLine is provided by highly efficient long life axial fans, realizing maximum power within a compact package.

SEMIKUBE is a more versatile product, allowing converter construction around a common DC link, including four quadrant converters, multiphase converters and newly developped 1500V inverter for solar central system.
