EVAL_3K6W_LLC_GAN

Overview

3600W, 385V to 52V LLC DC-DC demonstration board using CoolGaN™ 600V e-mode HEMT IGT60R070D1

This CoolGaN™ demonstration board is a 3600W full-bridge to full-bridge LLC DC-DC converter which converts 360V to 400VDC input voltage to a regulated 52V output. The superior switching characteristics of CoolGaN™
e-mode HEMTs result in very low losses, hence high-efficiency power conversion at high switching frequencies along with very high power density.

Summary of Features

  • 3600W load at 52V output
  • Input range 360VDC to 400VDC
  • 52V regulated output at 69A load continuous operation
  • Internal cooling (fan with ~ 400 LFM included)
  • Soft-start

Benefits

  • High-performance CoolGaN™ 600V  IGT60R070D1 70mΩ on the primary side and BSC026N08NS5 (80V, 2.6mΩ max.) as the synchronous FETs
  • Efficiency greater than 98% at 50% load and efficiency greater than 97% for loads higher than 20%
  • High power density 160W/in3 (box volume is calculated with excluding input and output connectors and the fan)
