Wideband Equivalent Circuit Model and Parameter Computation of Ignition Coil for Automobile Application
摘要
Abstract
Ignition coil acts as a transient voltage transformer in spark process.For predicting the wideband characteristic of ignition coil,a lumped circuit model is proposed.This model separates the winding into identical sections that simulate winding impedance quality.The parameter capacity between sections and winding-wingding capacity in each section are derived from finite element method computation plus curve fitting scheme.By means of finite element method,the parameter inductance which changes as fenquency varying is classified to high frequency inductance and low Frequence inductance.Through contrasting the measured and calculated results in frequency and time domain,reliability and feasibility of the presented method in this paper is verified.关键词
