Abstract

The present paper deals with the modelling of a Hall effect current sensor with open core magnetic concentrator. 3D magnetic field modelling is carried out using the finite element method (FEM) and Comsol Multiphysics software. Two rectangular core constructions are considered. Different geometric parameters of the magnetic concentrator are varied and their influence on the sensor characteristic is studied, with the aim of reducing the dependence on the output signal on the distance to the conductor. Of the studied parameters, core window length leads to the most significant change in the sensor characteristic. Future work can include the optimization of the sensor construction.

摘要

本文研究了一种带有开口磁芯磁集中器的霍尔效应电流传感器的建模。使用有限元方法（FEM）和Comsol Multiphysics软件进行三维磁场建模。考虑了两种矩形磁芯结构。改变磁集中器的不同几何参数，并研究它们对传感器特性的影响，目的是减少输出信号对到导体距离的依赖性。在所研究的参数中，磁芯窗口长度对传感器特性的影响最为显著。未来的工作可以包括传感器结构的优化。
