Cree SiC MOSFETs revolutionize HEV/EV power converters

November 1, 2013

Cree Inc. announces that Shinry Technologies, a premier high-tech enterprise focused on energy efficient applications in transportation and lighting, employed Cree’s 1200V C2M family of SiC MOSFETs in its new, high-efficiency, hybrid electric and electric vehicle (HEV/EV) power converters to achieve industry-leading 96 percent efficiency.  According to Shinry Technologies, Cree’s C2M SiC MOSFETS also enabled a 25 percent reduction in product size and reduced peak power losses by over 60 percent compared to the traditional silicon versions.

“Our customers care a great deal about efficiency, compact size and system weight and cost,” said Dr. Wu Ren Hua, CEO of Shinry Technologies.  “The new C2M family of SiC MOSFETs from Cree allows our new HEV/EV power converters for passenger cars and busses to deliver industry-leading efficiency of 96 percent in a compact size that is 25 percent smaller than current platforms not using Cree C2M SiC MOSFETs.”

Based in Shenzhen, China, Shinry Technologies Co., Ltd. specializes in creating HEV/EV DC-DC converter, on-board charger and rapid charger solutions for a market that demands high reliability, efficiency and compact size.  By implementing Cree’s advanced second-generation SiC MOSFETs in its latest 3-10 kW DC-DC converters designed for use in electric busses, Shinry achieved considerable efficiency improvement and significant size and weight reduction.  

“Cree is focused on delivering best-in-class energy efficiency through SiC innovation, so it’s very exciting to see our new C2M SiC MOSFET family being used to break barriers in HEV/EV power conversion,” said Cengiz Balkas, vice president and general manager, Cree Power and RF. “Shinry’s rapid adoption of Cree’s C2M MOSFETs provides state-of-the-art efficiency, power density and cost to their customers.  We are very pleased to have Shinry using our products.”

Introduced in March 2013, Cree’s C2M family of SiC MOSFETs have been demonstrated to achieve more than three times the power density of typical silicon technology in standard power supply designs.  Cree® MOSFETs have been actively employed in solar inverters, industrial power supplies, battery chargers, uninterruptible power supply (UPS) systems and several other applications.  These new 1200V and 1700V MOSFETs allow manufacturers to differentiate their products in the market through significant improvements in efficiency, reliability and/or power density, the latter of which can also lead to reductions in the size, weight, volume and, in some cases, even the total cost of power systems.

Packaged SiC MOSFETs from Cree are available from DigiKey, Farnell/Newark, Richardson and Mouser, and die are available from SemiDice.  For more information, please visit www.cree.com/power or contact a local Cree sales person or distributor.
