GaN Systems and xFusion announce first 100W/in3 data-center power supply
GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) and computing power infrastructure and services provider xFusion Digital Technologies Co Ltd have introduced the xFusion 3kW PSU, which – with its compact dimensions of 68mm x 183mm x 40.5mm – is claimed to be the first power supply unit with power density of 100W/in3, as well as 80 Plus Titanium efficiency of 96%. The data-center power supply – which supports 90~264V DC voltage and 180V~300V AC voltage input, 12V output – is being displayed in the GaN Systems booth #509 (Hall 9) at Power, Control and Intelligent Motion (PCIM) Europe 2022 in Nürnberg Messe, Nuremberg, Germany (10–12 May).
The increasing demand for more data and power combined with sustainability initiatives are driving changes in the data-center industry, notes GaN Systems. The switch to the firm’s power transistors has demonstrated increased performance for products with power levels from 800W to 6kW, delivering substantial operating, financial and environmental benefits, it is claimed.
“Customers implementing GaN Systems’ power semiconductors in their PSUs are seeing a continual increase in PSU power density, from 45W/in3 to 63/in3, 82/in3, and now to 100W/in3,” says CEO Jim Witham. “With these power density breakthroughs and efficiency improvements, the value proposition of GaN is undeniable, and we will see more PSU companies offering these solutions.”
GaN is gaining ground in data-center PSUs, says GaN Systems. With the growth of the data-center sector worldwide, operators are focused on profitability and reducing their CO2 emissions. For each set of 10 racks in the data center, GaN-based PSUs can increase profits by $3m, reduce the cost of operating a data center, and cut CO2 emissions output by more than 100 metric tons per year, it is reckoned. Companies designing with GaN are doubling the power density of legacy PSUs, reaching power densities of up to 100W/in3 with 96+% efficiency, resulting in power supplies half the size and half the power loss compared to silicon-based power supplies.
At PCIM 2022, GaN Systems is demonstrating xFusion, SoluM and other data-center PSUs as well as its EVKs and thermal management solutions. Also showcased, are solutions for mobile device charging, industrial power, and electric vehicles.
