Telcodium Partners with Transphorm to Introduce First-Ever Redundant Power Supplies Using GaN FETs

BOUCHERVILLE, Quebec–(BUSINESS WIRE)–Telcodium, a leader in power supply design, in collaboration with Transphorm Inc. today released the industry’s first redundant power supplies using gallium nitride (GaN) field-effect transistors (FETs).

Telcodium & Transphorm launch first 650V GaN redundant power supply–94% True System Efficiency, reduced TCO & more Tweet this Telcodium’s AC Series replaces a typical three-module power supply architecture (two power supply bricks and one intermediate bus converter (IBC)) with a single power module with redundant AC feeds. Telcodium’s power module operates at 94 percent True System Efficiency (TSE)* or higher—reducing average energy loss by 13 percent or more.

To achieve the same TSE with the typical three-module power supply, the bricks and IBC would each need to yield a 97 percent efficiency—which exceeds the 80Plus Titanium specification and has yet to be demonstrated by any power supply manufacturer. Further, the new module is 30 percent smaller than the abovementioned two bricks and eliminates the standalone IBC—freeing considerable, critical space inside a host system. The high TSE and size reduction are made possible by Telcodium’s innovative design. This design pairs patented front-end circuitry with the market’s only JEDEC-qualified 650V GaN FET, available from GaN semiconductor design and manufacturing leader Transphorm. The resulting AC Series enables data center, server and telecommunication manufacturers to develop smaller, high-performing systems that can virtually eliminate power supply-related failures.
