New 4kW GaN power supply reference design by Arrow, Nexperia and Yageo

Unleash the power of gallium nitride (GaN) technology with Arrow Electronics' latest innovation – an AC/DC power supply reference design capable of up to 4kW output. Developed by our in-house design team, this advanced power supply unit (PSU) is now available for integration into your own products.

High efficiency single phase 4KW isolated PSU

  • 150-270 V input GAN based totempole PFC @130KHz, 400V
  • GAN based LLC Full bridge isolated DC-DC @500KHz with silicon based full bridge SR, target efficiency 99%
  • 48V output ~80Amp with current sense (protection/set optional)
  • Fully Analog controller (PFC/LLC/SR) based solution.
  • Custom magnetics for Aux supply (flyback) and isolated LLC
  • Shelf products: filter caps/inductors, PFC chocked, isolated current sense transformers (LLC/PFC)
  • All BOM from Arrow portfolio

The PSU reference design is perfect for a wide range of applications:

  • Solar and wind energy conversion
  • Industrial robots
  • HVAC equipment
  • Fluid pumps
  • ATM machines, and general industrial automation and power supplies including UPS
  • E-bikes, power tools, and professional audio equipment.

Our 4kW reference design is at the forefront of the current trend to adopt GaN wide-bandgap transistors in applications above 1kW. This technology delivers numerous advantages, including smaller power-supply dimensions, cooler operating temperatures, and superior appliance energy ratings.

To realize this advanced design, our team utilized the latest GAN039-650NTB power transistors from Nexperia and worked with Yageo to develop specifications for the flyback transformer and resonant-circuit inductor. The GAN039-650NTB has cutting-edge device parameters, ensuring high reliability and low operating temperatures with simplified thermal management.
