一种应用于椭圆阵列式霍尔传感器的多导体测量串扰优化研究
A Multi-Conductor Measurement Crosstalk Optimization Study Applied to Elliptical Array Hall Sensors
摘要
Abstract
Circular array Hall sensors are widely used in the practical use of current sensors due to their ability to meet the requirements of low power consumption and high accuracy over a wide frequency range.In power distribution systems,rectangular cross-section conductors with small heights and large widths are usually used.In order to adapt to a variety of scenarios while maintaining measurement accuracy,an elliptical sensor array is proposed.When facing a large number of parallel conductors,the sensor is easily affected by the external mag-netic field.In order to improve the anti-interference performance of the sensor,a differential array based on the elliptical sensor array is constructed and inverted by the least square method.The current sets at different loca-tions inside the sensors are obtained by measuring the radial difference of the magnetic field.The measurement results show that the differential array has smaller crosstalk error and stronger anti-interference ability to exter-nal magnetic field compared with a single-ring type array of elliptical sensors of the same size,and the con-structed elliptical differential array sensor can effectively reduce the error when measuring the current carried by multiple rectangular conductors.关键词
