工程電路分析

內(nèi)容概要

　　本書首版于1962年，目前已是第八版。作者從3個(gè)最基本的科學(xué)定律推導(dǎo)出電路分析中常用的分析方法及分析工具。書中首先介紹電路基本參量及基本概念，然后結(jié)合基爾霍夫電壓和電流定律，介紹節(jié)點(diǎn)和網(wǎng)孔分析法及疊加定理、電源變換等常用電路分析方法，并將運(yùn)算放大器作為電路元件加以介紹；交流電路的分析開始于電容、電感的時(shí)域電路特性，然后分析RLC電路的正弦穩(wěn)態(tài)響應(yīng)，并介紹交流電路的功率分析方法，接著還對(duì)多相電路、磁耦合電路的性能分析進(jìn)行了介紹；本書還介紹了復(fù)頻率、拉普拉斯變換和s域分析、頻率響應(yīng)、傅里葉分析、二端口網(wǎng)絡(luò)等內(nèi)容。作者注重將理論和實(shí)踐相結(jié)合，無論例題、練習(xí)、章后習(xí)題還是正文中的應(yīng)用實(shí)例，很多都來自于業(yè)界的典型應(yīng)用，這也是本書的一大特色。

章節(jié)摘錄

　　Voltage We must now begin to refer to a circuit element, something best defined in general terms to begin with.Such electrical devices as fuses, light bulbs, re-sistors, batteries, capacitors, generators, and spark coils can be represented by combinations of simple circuit elements.We begin by showing a very general circuit element as a shapeless object possessing two terminals at which connections to other elements may be made （Fig.2.8）.There are two paths by which current may enter or leave the element.In subsequent discussions we will define particular circuit elements by describ-ing the electrical characteristics that may be observed at their terminals.In Fig.2.8, let us suppose that a dc current is sent into terminal A,through the general element, and back out of terminal B.Let us also assume that pushing charge through the element requires an expenditure of energy.We then say that an electrical voltage （or a potential difference） exists be-tween the two terminals, or that there is a voltage "across" the element.Thus, the voltage across a terminal pair is a measure of the work required to move charge through the element.The unit of voltage is the volt,2 and 1 volt is the same as 1 J/C.Voltage is represented by V or v.A voltage can exist between a pair of electrical terminals whether a current is flowing or not.An automobile battery, for example, has a voltage of 12 V across its terminals even if nothing whatsoever is connected to the terminals.According to the principle of conservation of energy, the energy that is expended in forcing charge through the element must appear somewhere else.When we later meet specific circuit elements, we will note whether that energy is stored in some form that is readily available as electric energy or whether it changes irreversibly into heat, acoustic energy, or some other nonelectrical form.We must now establish a convention by which we can distinguish be-tween energy supplied to an element and energy that is supplied by the element itself.We do this by our choice of sign for the voltage of terminalA with respect to terminal B.If a positive current is entering terminal A of the element and an external source must expend energy to establish this cur-rent, then terminal A is positive with respect to terminal B.（Alternatively,we may say that terminal B is negative with respect to terminal A.）
