Wolfspeed Silicon Carbide: More with Less

When datacenters are fitted with power supplies built with Wolfspeed’s Silicon Carbide (SiC) MOSFETs and diodes, they can deliver more computing power per square foot–with a lower electric bill.

Server & Telecom Power Supplies

A full 2% of all electrical energy in the U.S. is consumed by data centers, and that number is growing worldwide. Power supplies designed around Wolfspeed’s Silicon Carbide products improve thermal performance sufficiently to create up to 40% savings in energy costs on cooling alone. In the period from 2010 and 2020, servers running SiC devices will have contributed 620 billion kWh in energy savings. Imagine how much more energy can be saved over the next 10 years. Silicon Carbide also enables designers to meet the requirements for the 80+Titanium standard, and Wolfspeed’s products are ready to meet even tougher future standards.

Wolfspeed modules enable Sinexcel to shrink power quality solutions by 50% and improve peak efficiency to 99%

Wolfspeed WolfPACK™ power modules enabled Sinexcel Electric Company, a global power supply manufacturer, to achieve 50% size and 40% weight reductions in two of their products – significantly improving cabinet capacities for the data centers they power.

“To meet the growing need for a power quality solution that has higher efficiency, higher power density, smaller size and lighter weight, we partnered with Wolfspeed to utilize its industry leading Wolfspeed WolfPACK™ Silicon Carbide power modules into our most recently launched P5 series Active Power Filter (APF) and Static Var Generator (SVG). This is a groundbreaking application of high-power silicon carbide in Active Power Filter (APF) and Static Var Generator (SVG) and will dramatically improve performance and market competitiveness of our power quality solution.”

– Mr. Longteng Zhao, General Manager of Power Quality Division, Sinexcel
