Cree SiC MOSFETs Help Power Japans Growing Solar Energy Infrastructure


Sanix Incorporated selected Crees C2M silicon carbide MOSFETs for use in their latest solar inverters to achieve the best combination of system performance, reliability and pricing



DURHAM, N.C. – Cree, Inc. (Nasdaq: CREE) has announced that its C2M, 1200V, 80mOhm SiC MOSFETs have been selected by Sanix Corporation, Japan, to be designed into their new 9.9kW three-phase solar inverters for use in the construction of commercial photovoltaic systems in the fast-growing Japanese solar energy market.



"Through this partnership with Cree and their SiC technology, Sanix is able to capture more market share in the competitive Japan solar market," said Hiroshi Soga, general manager, Sanix Incorporated. "Crees silicon carbide MOSFETs were critical for Sanix to meet our efficiency and thermal design targets. SiC switches reduced losses in our inverter electronics by more than 30 percent versus the silicon super-junction MOSFETs we were considering. In addition to providing a large efficiency gain, Crees latest generation C2M SiC MOSFETs were priced competitively, making it possible to replace lower voltage, less rugged, and less efficient silicon MOSFETs."



Utilized in the primary power conversion stage of the solar inverter, Crees 1200V C2M0080120D MOSFETs feature faster switching characteristics and up to one-third the switching losses of comparably-rated 900V silicon super-junction MOSFETs. By significantly reducing switching losses, Crees SiC MOSFETs enable lower total system energy losses, higher frequency switching, and cooler operating temperatures. These benefits improve conversion efficiency and reduce the systems size, weight, complexity, and thermal management requirements. At the system level, performance is improved, cost is decreased, and lifetime of the inverter is extended.



"Cree is extremely pleased that Sanix has chosen to specify our C2M, 1200V SiC MOSFET technology in its new 9.9kW solar inverters. Cree® SiC power devices can provide significant advantages with regard to PV inverter efficiency, reliability, and cost, and will provide Sanix with a critical competitive advantage as they continue to expand their share of the Japanese solar market," said Cengiz Balkas, general manager and vice president, Cree Power and RF.



Demonstrated to achieve up to three times the power density of typical silicon technology, Crees C2M family of SiC MOSFETs are available in 1200V and 1700V, ranging from 1? to 25 m?. C2M MOSFETs have been designed into a range of industrial power applications since their March 2013 market introduction and continue to experience increasing demand. Cree is currently delivering production volumes of SiC MOSFETs to Sanix and other PV inverter manufacturers, as well as to makers of industrial power supplies, auxiliary power converters, battery chargers, and motor drives.
