Transphorm Releases 3.3kW GaN Reference Design
High-voltage bridgeless totem-pole PFC design simplifies AC to DC system development in server, automotive and industrial applicatiions
Transphorm has released a complete 3.3kW continuous conduction mode (CCM) bridgeless totem-pole power factor correction (PFC) reference design for high-voltage (HV) GaN power systems.
The technical blueprint is used to develop AC to DC applications including industrial applications, high-end front-end PFCs for merchant power supplies (servers, gaming, crypto mining, and similar multi-kW high density applications), and on-board chargers for plug in hybrid (PHEV) and battery electric vehicles (BEV).
“As demonstrated by customer end products, Transphorm’s high Q+R devices are proven to deliver what high-voltage GaN has always promised. Increased power density, efficiency, and performance with reduced system cost," said Philip Zuk, VP of technical marketing, Transphorm.
“Now, we are helping designers quickly capitalise on those benefits by eliminating design knowledge gaps. With our 3.3-kW reference design, we’re arming the industry with a roadmap that was several years in the making. We are excited to see what system innovations will be built upon this GaN foundation."
