Cree announce its new Silicon-Carbide, high-frequency power module
 
The new high frequency module, rated at 100-A current handling and 1200-V blocking, allows higher efficiency, compact and lighter weight systems that can result in lower total system costs compared to conventional silicon-based technologies.

Cree, Inc. continues to showcase the superior performance and reliability of its silicon-carbide (SiC) power technology with the introduction of the first commercially available all-SiC Cree® power module. The new high frequency module, rated at 100-A current handling and 1200-V blocking, allows higher efficiency, compact and lighter weight systems that can result in lower total system costs compared to conventional silicon-based technologies.

“An all-SiC module with these specifications enables us to meet our transit customers’ demands for reduced size and weight of auxiliary power converters, while meeting efficiency and cost targets,” said Fisal Al-Kayal, innovation and research engineer, Alstom Belgium Transport.

The module includes SiC MOSFETs and SiC Schottky diodes in a 50-mm half-bridge configuration rated to 150°C maximum junction temperature. The SiC components enable the module to be operated at exceptionally high switching frequencies that can reduce the size, weight and cost of the power conversion system. The new power module has demonstrated up to 100 kHz switching frequency. Target applications include high power converters, industrial motor drives, solar inverters and uninterruptible power supplies.

“The 1200-V, 100-A dual module extends our existing discrete MOSFET and diode products into higher power applications,” explains Dr. Mrinal Das, product marketing manager, Cree Power and RF. “The efficient switching characteristics of an all-SiC module should allow system designers to meet customer demands for reduced size, weight and cost of the end-system, while reducing global energy consumption. Already, Cree SiC power devices have eliminated an estimated one million metric tons of annual CO2 emissions – the equivalent to planting 95 million trees.”    

Parts are available for immediate shipping through Digi-Key Corporation and Mouser Electronics (CAS100H12AM1). Sample gate drivers are available upon request to Cree for module customers.
