Shunt-Based Isolated Current Sensing Module Reference Design with Delta-Sigma Modulator

TIDA-00080

Overview

This shunt-based, isolated current measurement unit enables high-precision current measurement without the use of current transformers (CTs). Isolation is achieved through the AMC1304 which integrates high voltage isolation and a Delta-Sigma modulator . This solution avoids the need to use CTs, which is highly valued by customers as it reduces board size, product weight, crosstalk and EMI in the system, and reduces mechanical requirements by replacing CTs with shunts. problems, potentially extending product life.

characteristic

● High-precision current/voltage measurement function
● Accuracy reaches 0.25% in the range of 0.5A to 10A
● 1% accuracy within the range of 10A to 200A
● No need to use CT for current sensing
● Mitigating crosstalk and EMI in the system
● Extend product life (reduce mechanical issues) and reduce board size
