TIDA-00080

Isolated delta-sigma modulator based AC/DC voltage and current measurement module reference design

TIDA-00080

Design files

Overview

This isolated shunt based current measurement unit enables high accuracy current measurement without the use of Current Transformers (CT). The isolation is achieved through the use of AMC1304 that incorporates both high voltage isolation as well as the Delta-Sigma Modulator. This solution eliminates the need for the CT which customers value due to the decrease in board size, reduced product weight, mitigation of cross talk and EMI in the system, and potentially increases product life through lower mechanical issues by replacing the CT with a shunt.

Features
  • High accuracy current / voltage measurement capability
  • 0.25% from 0.5A to 10A
  • 1% from 10A to 200A
  • Eliminate the CT for current sensing
  • Mitigates cross talk and EMI in system
  • Extend product field life (reduce mechanical issues) and shrinks board size
