GOLETA, Calif.—Transphorm Inc. released the first complete 3.3-kilowatt (kW) continuous conduction mode (CCM) bridgeless totem-pole power factor correction (PFC) reference design for high-voltage (HV) Gallium Nitride (GaN) power systems.
The technical blueprint is used to develop AC to DC applications:
High-end front-end PFCs for merchant power supplies (servers, gaming, crypto mining, and similar multi-kW high density applications)
On-board chargers for plug in hybrid (PHEV) and battery electric vehicles (BEV)
Broad industrial power supplies
