Power Factor Correction GaN Reference Design Simplified for Server, Automotive, and Industrial Applications

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
