Boston, MA 10/14/2014 (wallstreetpr) – Cree, Inc. (NASDAQ:CREE) expanded the 1.2-kV, six-pack power module family of silicon-carbide (SiC) with new 20-A. All the modules designed to suit 5–15-kW three-phase applications.
Cree’s all-SiC module
Designers are typically witness problems with Si-based inverters in their industrial power conversion systems. The inverters reduce efficiency of the power generation systems as it decreases in power density. So, the maintenance costs keep on increasing to resume the power generation.
Therefore, Cree, Inc. (NASDAQ:CREE) aims to address the constraints a designer observes in Si-based inverters. The company designs the module by utilizing owns’ Z-Rec SiC Schottky diode and C2M SiC MOSFET technology. The features of the modules reduce the switching loss due to the impact of the MOSFET’s zero turn-off tail current and Schottky diode’s zero reverse-recovery current.
Moreover, the new 20-A, usually, have advanced features that operate at lower junction temperature compared to similar Si IGBT modules. Hence, it helps the designers to take the advantage of the highly-efficient power products.
Transform power generation systems
Cree, Inc. (NASDAQ:CREE)’s six-pack power module family already tested in inverter platform by CCS020M12CM2 SiC Module of Cummins, Inc. It increased power rating of the inverters by 40% while reducing the power loss by 50% and also increased the overall efficiency by 5%, as said by Brad Palmer, Product Line Architect, and Cummins.
Mr. Palmer also mentioned that the new module will improve the power rating by four times higher than the traditional Si IGBT modules. He also said that Cummins will integrate the solution in its next-generation products to increase their efficiency.
Subsequently, Cree Power and RF’s General Manager and President, Cengiz Balkas said that the Sic power products are consistent at their system-level performance while addressing the traditional challenges.
Mr. Balkas also said the new six-pack modules achieved superior results at Cummins’ testing that enables to develop high-performance, cost-effective solution for the next-generation power conversion systems.
