Study and Simulation of Transition Process about Tigh-energy Ignition Coil for Motor Engine Burning Carbinol Fuel

提出一种研究高能点火互感电路过渡过程的新方法 .通过对磁介质磁化曲线采用数理统计方法拟合 ,找出拟合函数 ,然后运用四阶龙格 -库塔法求解微分方程 .文中求出初级电流瞬态解 ,同时给出 PSPICE软件仿真结果 .

A new method researching high-energy ignition coil transition process was advanced in this paper. Symbolic-statistics method was used to find fitting function of magnetization curve, and then the Runge-Kutta method was used to resolve differential equation. Finally primary current and simulation value by Pspice were shown.
