GaN Systems and xFusion introduce Data centre Power Supply


100W/in3 GaN-Based PSUs enable data centres to increase revenue and reduce operating costs and carbon footprint

At PCIM Europe 2022, GaN Systems and xFusion Digital Technologies have introduced the xFusion 3kW PSU, the world’s first 100W/in3 with 80 Plus Titanium efficiency solution.

The increasing demand for more data and power combined with sustainability initiatives are driving change in the data centre industry. The switch to GaN System’s power transistors has demonstrated increased performance for products with power levels from 800 Watts to 6kW delivering substantial operating, financial, and environmental benefits.

Xfusion’s 3kw PSU features 80 Plus Titanium efficiency of 96 percent, a compact design with dimensions of 68mm x 183mm x 40.5mm, and supports 90~264V DC voltage and 180V~300V AC voltage input, 12V output.

“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," said Jim Witham, CEO of GaN Systems. "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 centre PSUs. With the growth of the data centre sector worldwide, operators are focused on profitability and reducing their CO2 emissions. For each set of 10 racks in the data centre, GaN-based PSUs can increase profits by $3 million, reduce the cost of operating a data centre and CO2 emissions output by more than 100 metric tons per year.

GaN Systems is demonstrating xFusion, SoluM, and other data centre PSUs as well as its EVKs and innovative thermal management solutions at PCIM. Additionally, solutions for mobile device charging, industrial power, and electric vehicles will be on show.
