GaN FETs boost efficiency in electric vehicle chargers
The role gallium-nitride FETs play in the design of an EV charging circuit help illustrate how these wide-bandgap semiconductors facilitate energy efficiency. FENG QI, TRANSPHORM THE PHASE-SHIFT FULL BRIDGE (PSFB) is a classic topology for applications that must accommodate a wide range of operating voltages, as with battery chargers. A PSFB converter generally uses four […]
650-V GaN FETs with 4-V threshold
Transphorm today announced availability of its third generation (Gen III) 650-V GaN FETs. Power transistors built on Gen III technology yield lower electromagnetic interference (EMI), increased gate noise immunity, and greater headroom in circuit applications. The latest evolution of the award-winning platform stems from knowledge gained by the Transphorm team working with customers on end […]

First GaN-based AC-DC power supply with totem pole PFC topology
Transphorm Inc. stated today that the recently announced high-efficiency TET3000-12-069RA power supply marks another GaN industry milestone. Developed by Bel Power Solutions, a Bel group company, the AC to DC front-end TET3000 uses a GaN-based bridgeless totem-pole power factor correction (PFC) topology to achieve greater than 96 percent efficiency. The power supply will be displayed during […]
PODCAST Umesh Mishra: GaN and power to the people and planet
The wide bandgap semiconductor Gallium Nitride (GaN) has been out of the lab and into products in some markets for almost a decade. But this is a new and exciting time for GaN as it finds its way into rapidly expanding high-speed, high-power applications like data centers, motor drives, EVs, and more. A significant player in this […]
