Texas Instruments LM5023 | Demoboard PMP8740

2-kW industrial AC/DC battery charger reference design with 92% full-load efficiency

Overview

TopologyFlyback Converter
Input voltage195-265 V
Output 112 V / 4.2 A
IC revisionA

Description

This reference design is a module that can be set as standard power supply or a battery charger. The output voltage ranges from 0 V to 32 V at a maximum current of 62.5 A. It consists of four boards, a boost PFC, a phase shift full bridge, a small daughter board (hosting the microcontroller), and a display board with three LEDs and four push-buttons. The input voltage range is universal: 90 VAC to 264 VAC and the input current is limited to 10 Arms, which limits the input power below 200 VAC. The microcontroller interfaces the power supply to an operator and controls all functions, including enabling and shutting down the PFC and DC/DC stage, setting different output voltage levels and charging current limits.

Features

  • 93.5% peak efficiency optimizes thermal management of the module
  • Serial interface gives users the ability to easily parallel up to 10 hardware modules
  • Primary/Secondary or stand-alone configuration for battery charging or standard power supply unit
  • Two raw displays and four pushbuttons simplify configuration
  • Pre-defined levels for li-ion, lead-acid and gel batteries

Typical applications

  • Digital controlled industrial AC/DC
