Transphorm, Inc. and Bel Power Solutions stated that six of Bel’s Titanium Efficiency Power Supplies use Transphorm’s high voltage GaN FETs. This news indicates the growing trend of high performance, wide bandgap power supply units (PSUs) being deployed in datacenter servers, routers, and network switches. The six GaN-based TET series PSUs are AC to DC front end supplies. They include the TET3000 series, the industry’s first AC-DC supplies to achieve Titanium efficiency with GaN being used in the AC-to-DC bridgeless totem-pole power factor correction (PFC) power stage—a product that has since been modified using the same circuitry with firmware improvements to become the TET3200 series based on customer interest in higher power output. The remaining four TET series range in power levels from 1.5 to 2.5 kW and are packaged in standard 1U or common redundant power supply (CRPS) rack mount form factors. The entire family delivers greater than 96% efficiency at high line with a main output of 12 VDC, earning the PSUs an 80 Plus Titanium rating.
