內容簡介

本書從最基本的科學定律(歐姆定律、基爾霍夫定律)入手,導入了電路分析的常用分析方法和分析工具。本書首先介紹電路的基本組成及基本概念和參量,然後結合基爾霍夫定律,輔以適量例題及習題介紹支路電流法、結點電壓法、電源模型及等效變換、疊加定理和戴維南定理。暫態回響分析以一階電路為主,詳細分析其三種回響模式。交流電路分析以電容和電感的交流特性為基礎,分析了RLC串並聯電路的正弦穩態回響及其功率計算方法,還對三相電路原理、三相異步電動機的原理及控制做了詳細介紹。本書注重理論與實踐相結合,採取中英文對照的方式,強化學生的專業英文能力,為後續課程學習及深造打下良好基礎。
本書可作為高等院校電子信息類、電氣類、計算機類等相關專業師生的中英文雙語教學用書,也可作為從事電子技術、電氣工程、通信工程領域的工程技術人員的參考書。
