摘要

提出一种新型的闭环式双铁芯霍尔电流传感器模型。选用的双铁芯

一个是带有放置霍尔器件的缝隙的、用于直流电流传感器的铁芯

另一个则是用于交流电流传感器的无缝隙铁芯。这2种铁芯的结构和材料借助于理论分析和仿真计算来确定。实验结果表明:这种新型的双铁芯电流传感器不仅能消除闭环霍尔电流传感器的频率特性中的台阶现象

并且还能保持较好的精度和线性度。

Abstract

A novel closed-loop dual iron-core current sensor is presented. Two type cores structures are chosen

one is a DC current sensor core with a gap for Hall chip

and another is AC current sensor seamless core. The structure and material of the dual iron-core are determined by means of theoretical analysis and simulation calcutation. Experimental results show that the new type dual iron-core current sensor can not only eliminate the steps phenomenon in the frequency characteristic of closed-loop Hall current sensor

but also keep good precision and linearity.
