Since data centers vary in size, the savings are based on a 10-Rack unit of measure. GaN Systems concluded that significant energy and cost savings are achieved by switching from silicon-based PSUs to GaN-based PSUs. GaN brings higher efficiency, higher power density, lower cost, and increased sustainability to the data center ecosystem. New efficiency mandates, increasing power, and data demands, and the shift to “ Dollar per Density,” where density is a measure of size and power of the power supply, spur the immediate need to change data center economics with smaller, more efficient, and reliable power supply design. The combined GaN BTP-PFC with GaN LLC resonant converter enables designers to create lower-cost power supplies that meet demands to deliver more power in a smaller footprint and new energy efficiency requirements, including European Union’s “Lot 9” 2023. GaN Systems introduced a high efficiency, highest power density 3kW Bridgeless Totem Pole (BTP) PFC + LLC Resonant Converter Power Supply Unit (PSU) that exceeds the 80 PLUS Titanium standard.
