摘要
低压电感电路当电感大于95mH时，最小点燃电流MIC与电源电压无关；当电感小于95mH且电源电压小于20V时，MIC随电源电压不同而呈现不同的直线关系；若电源电压大于20V且电感小于0．2mH时，MIC与电感量无关。本文利用放电电流线性衰减模型和抛物线衰减模型分析了低压电感电路最小点燃电流和电感之间的这种关系，给出数学关系式，并分析了误差原因。
For low voltage reluctance circuits,when the value of reluctance L is greater than 95 mH,the minimum ignition current(MIC) is irrelative to the supply voltage(E),and when L<95mH and E<20V MIC is linear corresponding to different supply voltage in MIC-L curves,and when E>20V and L<0. 2mH MIC is irrelative to L. In this paper,the relationship of L and MIC is discussed by using linear and parabolic current attenuation models,the mathematical models were given and the error was analyzed.
