摘要
对带非线性负载的无畸变传输线瞬态分析问题,利用Volterra积分方程,建立了一种半解析方法.该方法利用Baum-Liu-Tesche (BLT)方程得到频域输入导纳、短路电流,然后利用级数展开和傅里叶变换的性质,得到Volterra 积分方程中输入导纳、短路电流的瞬态解析表达,简化了Volterra积分方程,并可以避免奇异积分.
Abstract
A semi-analytic method based on the Volterra integral equation is used to calculate the transient responses of the distortionless transmission line with nonlinear loads.In this method,the frequency domain input admittance and short-circuit current are obtained by Baum-Liu-Tesche(BLT) equation,then the time domain input admittance and short-circuit current analytic expression in Volterra integral equation are obtained by series expansion and analytic Fourier transform,and the Volterra integral equation can be simplified,also the integral singularity can be prevented.
