摘要：
为了对微型磁通门的结构进行优化设计以降低微型磁通门功耗，通过仿真方法研究了微型磁通门的铁芯形状及绕线方式对磁通门激励电流和输出信号的影响。对缩比结构微型磁通门进行改进，提出一种采用多孔铁芯结合激励线圈/感应线圈交错缠绕的微型磁通门结构。采用这种结构，可以有效降低微型磁通门传感器的激励电流从而降低磁通门功耗。与已报道的经过优化设计的缩比结构微型磁通门相比较，由于这种结构引起的漏磁较小，能更有效的降低激励电流并提高灵敏度。

Abstract：
In order to reduce the power consumption of micro-fluxgate through optimize the structure, the effect of core shape and winding way on the excitation current and output voltage were studied through simulation. A new porous core structure combined with the interleaved winding excitation coil and induction coil were designed based on improving the traditional contracted core structure. With this structure, the excitation current of the micro-fluxgate sensor can be reduced effectively, indicating that the power consumption of the fluxgate can be reduced. This structure has smaller magnetic flux leakage, which is more effective to reduce the excitation current and improve the sensitivity of fluxgate compared with the contracted core structure which had been reported. Comparison with the contracted core structure which had been reported, the proposed structure effectively reduces the excitation current and improves the sensitivity of fluxgate because of smaller magnetic flux leakage.
