摘要
针对铁心线圈电感非线性问题,利用ansoft有限元分析软件,分析了铁心对线圈电感的影响。研究结果表明:铁心会大大增加线圈的电感,但随着励磁电流的增加线圈的电感会先增加后减小;当铁心内部含气隙时,气隙的位置和大小都会影响电感的变化率。
For the research of nonlinear problems in core coil inductance,use ANSOFT finite element software to analyze the impact of core on coil inductance.The results show that the core will greatly increase the coil inductance,but with the increase of excitation current,the coil inductance will first increase and then decrease;when the core coil has air gap,the location and size of the gap will affect the rate of inductance.
