自动化专业英语第四版课文翻译
自动化专业英语第四版课文翻译Unit 1现在工业电子系统使用的是被称为晶体管的装置。
每一类型的晶体管有区别于其他晶体管的不同特点和操作条件。
在讨论的第一部分，我们来关注双极性晶体管。
从结构上看，这个晶体管被描述为双极性的，是因为它有两个不同的电流载体极性。
空穴是阳极电流载体，而电子是阴极电流载体。
这两个不同性质的半导体晶体通过一个公共部分连接在一起。
这个装置的结构类似于两个二极管背靠背连接，其中一个晶体充当另外两个晶体的公共部分。
中间的材料通常被做得比外面的两片都要薄。
图1.1表示的是此晶体管的结构，原件名称，和不同双极性晶体管的语义符号。
一个双极性晶体管主要被用做放大器来限制流经它的电流。
电流从电源流入发射极，经过基极，再流出集电极。
集电极的电流量通常被定义为晶体管的输出量。
集电极电流由基极电流中的一小部分控制。
这个关系被描述为电流增量或β。
数学表达式如下：电流增量=集电极电流：基极电流。
公式中希腊字母△表示变化的值。
它用来表示当有交流输入时晶体管的响应。
这种类型的状态被称为动态特性。
公式中的△的省略部分表示直流或静态工作条件。
所有从发射极进入晶体管的电流被定义为发射极电流。
集电极电流Ic通常小于Ie。
Ie和Ic的不同归因于基极电流。
从数学角度看，Ib=Ie-IcUnit 2一个运算放大器的内部结构相当复杂，常常包含大量的分立元件。
一个运算放大器的使用者通常不需要关心它的内部结构。
然而，对于如何理解内部电子电路的完成却是有所帮助的。
这就允许使用者来观察设备是如何工作的，以及表明它作为一个功能单元的一些局限性。
运算放大器的内部电子线路可以被分为三个功能单元。
图1.7即是一个运算放大器内部功能的简图。
注意每一个功能都被附在一个三角形内。
电子图表中用三角形来表示放大功能。
这个简图显示了运算放大器有三个基本的放大功能。
这些功能一般叫作放大级。
一个放大级包含一或更多有源器件，所有相联元件需实现放大。
第一阶段或一个运算放大器的输入常常是一个差动放大器。

电气自动化专业英语翻译4-5
电气自动化专业英语（翻译4、5）数字电子4.1数字的概念4.1.1什么是数字信号(1) 一个历史例子。
"听，我的孩子们，你们将会听到保罗·瑞维尔午夜策马飞奔的传奇，"根据朗费罗的诗，保罗·瑞维尔通过波士顿老北教堂的钟楼那里给新英格兰农民发信号。
（如果英军今晚无论是从陆地还是从海上来犯，在老北教堂钟楼的拱门上高挂一盏灯笼作为信号）"一盏灯笼表示从陆地来，两盏灯笼表示从海上来" 。
那就是说，如果英国军队从波士顿陆地向康科德前进，展示一盏灯，如果他们穿过Mystie 河走间接航线，两盏灯将被展示。
爱国者们收到的消息就是数字形式的编码。
我们今天将说这两个" 位" 的信息通过代码运传送(严格地说，二位能表明4 个可能消息，并且要求可分辨的灯，一个红灯和一个白色的灯) . 第一个灯光通知英国军队正前进，第2 盏灯指示他们通过什么路线来。
因为想象只有两条路，信息的第二位能被解释为表明两条路线之一。
如果信息能被一系列的YES/NO所定义，信息就能以数字形式确定。
每个变量只可能有两种状态在传送信息方面使用。
这种方法把信息简化为一系列是/ 不看起来有局限性，但是这种方法实际上十分有用。
数目可以以基数2表示，字母表可以表示成数字代码。
的确，有限输出的任何情形都可以被简化成数字代码。
具体的，n位数字能描述成2n 个可能状态。
如同在我们的历史例子中，数字通讯能用明确定义的代码在两种情况下都通知到大家。
(2) 瑞维尔通讯码分析。
为了更进一步确定数字的信息的概念，我们将定义两个来描述保罗瑞维尔通信系统的数字变量，让B 描述是否英国人正来，并且L 描述他们正来的路线。
数学变量，B和L，是不平常的数学变量，因为每一个只能有两个值。
我们可以用我们希望的任何名字给两值命名：是/ 不，真/假，一/ 0，高/ 低，甚至黑色/白色。
当这类数学被通过符号逻辑用于哲学论据分析时，变量的值被叫对还是错，根据逻辑命题被阐述的正确性。

[11]GTOs are available with asymmetric and symmetric voltage-blocking capabilities which are used in voltage-fed and currentfed converters, respectively． [12]GTOs are used in motor drives, static VAR compensators (SVCs), and AC/DC power supplies with high power ratings. When large-power GTOs became available they ousted the force-commutated, voltage-fed thyristor inverters.

[4] If the reverse voltage exceeds a threshold value, called the breakdown voltage, the device goes through avalanche breakdown, which is when reverse current becomes large and the diode is destroyed by heating due to large power dissipation in the junction.

[7] Basically, thyristor is a three-junction P-N-P-N device, where P-N-P and N-P-N component transistors are connected in regenerative feedback mode. The device blocks voltage in both the forward and reverse direction (symmetric blocking).

[6] Often, it is a family name that includes SCR, TRIAC, GTO,MCT, and IGCT. Thyristors can be classified as standard, or slow phase-control-type and fastswitching, voltage-fed inverter-type. The inverter-type has recently become obsolete.

[5] Thyristors, or silicon-controlled rectifiers (SCRs) have been the traditional workhorses for bulk power conversion and control in industry. The modern era of solid-state power electronics started due to the introduction of this device in the late 1950s.

[15] The introduction of insulated gate bipolar transistors in the mid-1980s was an important milestone in the history of power semiconductor devices．They are extremely popular devices in power electronics up to medium power range and are applied extensively in DC/AC drives and power supply systems. They ousted BJTs in the upper range, and are currently ousting GTOs in the lower power range.

[16] An IGBT is basically a hybrid MOSgated turn-on/off bipolar transistor that combines the advantages of both a MOSFET and BJT. Its architecture is essentially similar to that of a MOSFET, except an additional P+ layer has been added at the collector over the N+ drain layer of the MOSFET.

[3] They are also used in feedback and the freewheeling functions of converters and snubbers. A typical power diode has P-I-N structure, that is, it is a P-N junction with a near intrinsic semiconductor layer (I-layer) in the middle to sustain reverse voltage.
