Shinry and Cree Raise the Bar for State-of-the-Art EV Power Converters

Shinry Technologies Co. Ltd. has employed Cree’s 1200-V 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 buses 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 is a National High-tech Enterprise with core business focused on energy-saving technologies such as LED drivers and "new energy" opportunities such as electric vehicles. Shinry also is a National 863-Project Enterprise providing high efficiency, high power, intelligent and high reliability electrical electronic proposal. The company's green lighting power supply offering covers LED indoor & outdoor drivers, LED display screen drivers and LED lighting intelligent control system drivers. As a National High-tech Enterprise, Shinry has built a long-term cooperation with Tsinghua University since 2006.

The dc-dc converters that use the Cree SiC MOSFETs were developed at the company's new energy auto/car power supply R&D center that was established in 2006. Shinry 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 to 10-kW dc-dc converters designed for use in electric buses, 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."
