本文对用恒流源驱动的环状矩磁性铁氧体磁心线路的性能作了分析。文中分析的电路包括:具有各种负载的单个磁心线路、多路磁心线路、多级磁心线路以及具有空气隙的磁心线路。文中所介绍的分析方法是根据 A.Papoulis 未发表的文章扩展而来的。各种磁心线路的响应或端特性可用一组非线性方程解析地来描述是众所周知的。文中用一种图解法来解非线性微分方程,用相平面轨跡法来解非线性积分方程,并给出一些实验结果,以证实理论方法,实验测得的值与理论计算值很接近。
This paper analyzes the performance of a toroidal magnetic ferrite core line driven by a constant current source. The circuit analyzed in this paper includes a single core with a variety of loads, a multiplexed core, a multistage core, and a core with an air gap. The analytical methods described in this article are based on unpublished articles by A.Papoulis. It is well-known that the response or end properties of various magnetic core lines can be analytically described by a set of nonlinear equations. In this paper, a graphical method is used to solve the nonlinear differential equation, and the phase-plane trajectory method is used to solve the nonlinear integral equation. Some experimental results are given to verify the theoretical method. The experimental values are close to the theoretical ones.
