Gospower uses Cree’s Wolfspeed 650V SiC MOSFETs for common redundant power supply

Cree Inc of Durham, NC, USA says that China-based power electronics converter maker Shenzhen Gospower Digital Technology Co Ltd will utilize its Wolfspeed 650V silicon carbide MOSFETs for next-generation common redundant power supply (CRPS) solutions. As the demand for cloud-based storage continues to expand rapidly, Gospower will leverage Wolfspeed’s SiC technology to deliver power efficiencies that will boost China’s power server market and better support the country’s digital storage demands.

Server and computing power supply demands are increasing significantly due to rapid developments in the cloud, artificial intelligence, distributed storage and 5G industries. Cree says that its Wolfspeed 650V silicon carbide MOSFETs offer high efficiency through low switching and conduction losses, as well as high-power-density features including smaller footprints, lighter weight and fewer components. Customers benefit from lower total cost of ownership through the more efficient use of power, reduced cooling requirements and what is claimed to be industry-leading reliability, enabling faster rollout of server power supply solutions.

“To meet the growing need for a power supply solution that has higher efficiency, smaller size and high power density, we partnered with Cree to utilize its Wolfspeed 650V silicon carbide MOSFETs to create an application that will help transform the Chinese server market,” says Gospower’s CEO Ruan Shiliang.

Gospower developed a 2400W/2600W 185mm CRPS solution that utilizes Wolfspeed silicon carbide MOSFETs in the totem-pole bridgeless power factor correction (PFC) design. This device creates a highly efficient, reliable and cost-effective solution that operates under higher temperatures and features lower switching losses, zero reverse recovery and high power density, all in a smaller size.

“This solution will help advance the power supply sector and is a testament to the innovations that are made possible by silicon carbide when we collaborate with industry leaders such as Gospower,” says Cree’s CEO Gregg Lowe.
