摘要

本文介绍了一种使用高精度ACS712霍尔传感器的精确、经济的低量程(5 A以内)交流电流传感方案。采用ATmega微控制器对霍尔传感器输出信号进行处理和数据采集，使系统具有自依赖性。由于ACS712霍尔传感器的高运行速度和宽耐温范围，提高了系统的可重复性。设计了一种电流传感系统的原型，可感应高达5 A (ac)，精度为0.01 A，分辨率为10位。仿真和实验验证包括在高质量的电流传感能力方面捍卫设计的性能。

Implementation of a high accuracy ac current sensing scheme using hall-sensor

The paper represents an accurate and economic low range (up to 5 A) ac current sensing scheme using high precision ACS712 hall-sensor. ATmega microcontroller is used in processing signal and for data-acquisition from the hall-sensor output in order to make the system self-dependency. The reproducibility of the developed system is increased due to high speed operation and wide temperature-tolerance range of ACS712 hall-sensor. A proto-type of current sensing system is designed to sense up to 5 A (ac) with a precision of 0.01 A and resolution of 10 bit. Simulation and experimental validations are included to defend performance of the design with regard to high quality current sensing ability.
