摘　　要：在一些电路教材中常把带滤波器的整流电路作为一个实例,用以讲述用傅立叶级数的谐波分析方法来求解非正弦电路。问题是在这些教材中没有说明整流器的具体结构,读者通常都会把整流器理解为二极管整流器,导致概念上出现混淆。众所周知,傅立叶级数的谐波分析方法的应用是基于线性叠加,不能用来分析非线性电路。本文试图就此澄清有关基本概念,以便优化理论教学。In some circuit textbooks the rectifier circuit with the filter has been used as an example to illustrate the harmonic analysis of nonsinusoidal circuit adopted Fourier series. The problem is that in these textbooks the concrete structure of the rectifier is not explained clearly, thus readers would usually view the rectifier as diode rectifier, resulting in conceptual misunderstanding. As we all know, the application of harmonic analysis with Fourier series is based on linear superposition, which cannot be used to analyze nonlinear circuit. This paper attempts to clarify some basic concepts to make some meaningful contribution to theoretical teaching.
