DURHAM, NC -- Cree, Inc. has expanded the award-winning, silicon-carbide (SiC), 1.2-kV, six-pack power module family with a new 20-A, all-SiC module ideally suited for 5–15-kW, three-phase applications. Based on Cree’s C2M™ SiC MOSFET and Z-Rec® SiC Schottky diode technology, the six-pack module enables designers to unlock the traditional constraints of power density, efficiency and cost associated with Si-based inverters used in industrial power-conversion systems.

Cummins, Inc., a global power leader in electrical power-generation systems, has tested and confirmed the capabilities of Cree’s all-SiC, 1.2-kV, six-pack power module family in their inverter platform. Furthermore, engineers at Cummins are working to integrate and exploit these capabilities with their next-generation, high-efficiency products. 

“Cree’s new, 1.2-kV, all-SiC, six-pack module family will allow us to increase the power rating of our class-leading inverter by 40 percent while reducing power losses by 50 percent to increase efficiency by 5 percent,” said Brad Palmer, power electronics product line architect, Cummins, Inc. “This new power module is a significant technological advancement, capable of outperforming Si IGBT modules with four times the current rating. We are delighted to have had the opportunity to be an early tester of this technology and look forward to incorporating it in our products.” 

The new all-SiC, 1.2-kV, 20-A six-pack features the industry’s lowest switching losses due to the zero turn-off tail current in the MOSFET and the zero reverse-recovery current in the Schottky diode. When compared to similar Si IGBT modules, the new Cree® 20-A six-pack module operates at a much lower junction temperature, allowing designers to aggressively pursue new paradigms in high frequency and power density without compromising on efficiency. 

“Cree SiC power products consistently allow our customers to overcome age-old design challenges and achieve superior system-level performance that is simply not possible with Si-based systems,” said Cengiz Balkas, general manager and vice president, Cree Power and RF. “The results achieved by Cummins with our new, all-SiC, six-pack modules enable the high performance required to develop efficient and cost-effective, next-generation power-conversion products.” 

Cree’s new all-SiC, 1.2-kV, 20-A, six-pack power module (part number CCS020M12CM2) and companion gate driver evaluation board (CGD15FB45P) are available at authorized distributors, including MouserDigi-Key, and Richardson RFPD/Arrow RF & Power.
