GaN-Based 3KW Full Bridge LLC Resonant Converter

Overview

TopologyLLC Resonant Converter
Input voltage380-400 V
Switching frequency250-450 kHz

Description

The full bridge LLC resonant converter design, integrating GaN Systems’ 650V Enhancement mode GaN transistors, exceeds the 80+ Titanium standard for power supply units (PSUs), achieving high power density (AC/DC PSU) above 100W/inch3 and high efficiency of more than 96 percent.

Features

  • High density: 146W/inch3 (including air-forced cooling)
  • High efficiency: Peak efficiency > 98%
  • Small size: <30mm height and meets low profile 1U datacenter PSU form factor
  • High switching frequency with maximum up to 450 KHz
  • Comprehensive system protections such as over current, short circuit, and over voltage

Typical applications

  • LED Lighting Drivers
  • Solar Inverter
  • High Power Adapters, Laser Drivers
  • Consumer, Industrial and Datacenter High Density Power Supply, Uninterruptable Power Supplies, Wireless Power Transfer
