Description

The EPC91110KIT evaluation board is a 5.5 kW, 400 V to 50 V 8:1 fixed ratio isolated converter evaluation board featuring the EPC2305 GaN FET, rated at 150 V, 2.2 mΩ (typical). The EPC91110KIT comprises 4ea 100 V to 50 V modules, connected in series on the high voltage side and in parallel on the output side, and can deliver 1.375 kW continuous power per module.

Features

  • High efficiency and high power-density isolated 400 V to 50 V converter
  • Fixed ratio (8:1) converter using four LLC modules configured in ISOP (Input-Series Output-Parallel)
  • Full-load (5.5 kW) efficiency of 98 % and peak load efficiency of 98.2 %
  • Self-balancing of the input voltage of each module
  • Uses 150 V-rated GaN transistors with better figures of merit than 650 V-rated devices used in equivalent 2-level topologies
  • Planar LLC transformer designed to meet isolation requirements per IEC 60950-1
  • Meets OCP ORv3 size requirements
  • Simple assembly
  • No special components

Typical applications

  • Industrial automation and robotics
  • Telecom and 5G Power Supplies
  • Medical equipment
  • EV Chargers
