摘要/Abstract

摘要： 磁芯损耗是磁芯发热最重要的原因，为了进一步对磁芯损耗的模型和机理进行研究，文章首先概述了磁芯材料对霍尔电流传感器发热的影响，阐述了霍尔效应、霍尔电流传感器的工作原理以及磁芯的损耗理论。其次基于含不同材料磁芯霍尔电流传感器的仿真结果与温升实验数据，发现非晶合金/纳米晶合金磁芯的温升效应显著低于硅钢磁芯，且越薄的磁芯叠片厚度对磁芯和传感器的发热具有越明显的抑制作用。该研究在一定程度上可以指导霍尔电流传感器的磁芯选型与设计。

Abstract: Core loss is the most important reason for core heating. In order to further study the model and mechanism of core loss, this paper first summarizes the influence of core materials on the heating of Hall current sensor, and expounds the Hall effect, the working principle of Hall current sensor and the loss theory of magnetic core. Secondly, based on the simulation results and temperature rise experimental data of Hall current sensors with magnetic cores of different materials, it is found that the temperature rise effect of amorphous alloy/nanocrystalline alloy magnetic core is significantly lower than that of silicon steel magnetic core, and the thinner the lamellar thickness of magnetic core has a more obvious inhibition effect on the heating of magnetic core and sensor. The research can guide the core selection and design of Hall current sensor to some extent.

Key words: Hall current sensor; silicon steel core; amorphous/nanocrystalline alloy core; core loss
