摘要
Abstract
For the market demand on high current sensors with performance like high accuracy,low offset current and low offset current temperature drift,CSNX1000 high current sensor is developed based on the anisotropic magnetoresistance(AMR)sensor of HMC1061,the application specific integrated circuit ASIC of HEBRIDE and optimized magnetic core design.The analysis of magnetic simulation and thermal simulation together with the product functional validation test results verify that the design meets the current sensor requirements specification,e.g.,the rated measuring current is 1000 A.t rms,DC accuracy is±0.4％,offset current is±0.4 mA,and offset current tem-perature drift is less than±0.2 mA is better than other type of high current sensors with same measuring range of primary current.关键词
