如果VS的控制极没有输入触发脉冲Ug，VS仍然不能导通，只有在U2处于正半周，在控制极外加触发脉冲Ug时，晶闸管被触发导通。画出它的波形（c）及（d），只有在触发脉冲Ug到来时，负载RL上才有电压UL输出。Ug到来得早，晶闸管导通的时间就早；Ug到来得晚，晶闸管导通的时间就晚。通过改变控制极上触发脉冲Ug到来的时间，就可以调节负载上输出电压的平均值UL。在电工技术中，常把交流电的半个周期定为180°，称为电角度。这样，在U2的每个正半周，从零值开始到触发脉冲到来瞬间所经历的电角度称为控制角α；在每个正半周内晶闸管导通的电角度叫导通角θ。很明显，α和θ都是用来表示晶闸管在承受正向电压的半个周期的导通或阻断范围的。

系统响应时间过长是交互式系统中用户抱怨多的问题，除了响应时间的长短外，用户对不同命令在响应时间上的差别亦很在意，若过于悬殊用户将难以接受；用户求助机制宜采用集成式，避免叠加式系统导致用户求助某项指南而不得不浏览大量无关信息；错误和警告信息必须选用用户明了、含义准确的术语描述，同时还应尽可能提供一些有关错误恢复的建议。此外，显示出错信息时，若再辅以听觉（铃声）、视觉（颜色）刺激，则效果更佳；命令方式是菜单与键盘命令并存，供用户选用。借助CASE工具构造界面原型，并真正实现设计模型软件模型一旦确定，即可构造一个软件原形，此时仅有用户界面部分，此原形交用户评审，根据反馈意见修改后再交给用户评审，直至与用户模型和系统假想一致为止。

在圆盘上产生一转矩。在20%～40%的动作电流整定值下，圆盘开始旋转。此时由于扇齿与蜗杆没有咬合，故继电器不动作。当线圈中的电流增大至整定电流时，电磁力矩大于弹簧的反作用力矩框架转动，使扇齿与蜗杆咬合，扇齿上升。此时继电器的动铁在扇齿顶杆的推动下，使导磁铁右边气隙减少，左边气隙增大，因而动铁被导磁铁吸合，使继电器触点动作。当继电器线圈中的电流为整定值时，感应元件的动作时限与电流的平方成反比。随着电流的增加，导磁体饱和，动作时限逐渐趋于定值。当线圈中的电流大到某一电流倍数时，电磁元件瞬时动作，因而继电器的动作时限具有有限反延时的特性。继电器具有若干抽头，用以调整感应元件与电磁元件的动作电流。另外用倍流螺钉改变动铁与电磁铁之间的气隙来调整电磁元件动作电流。

俗称耐压。常用可控硅的VRRM/VDRM一般为几百伏到一千伏。⒊控制极触发电流（IGT），俗称触发电流。常用可控硅的IGT一般为几微安到几十毫安。在规定环境温度和散热条件下，允许通过阴极和阳极的电流平均值。封装形式编辑常用可控硅的封装形式有TO-TO-TO-202AB、TO-TO-220ABC、TO-3P、SOT-TO-TO-SOT-SOT23-3L等用途编辑普通晶闸管基本的用途就是可控整流。大家熟悉的二极管整流电路属于不可控整流电路。如果把二极管换成晶闸管，就可以构成可控整流电路。以简单的单相半波可控整流电路为例，在正弦交流电压U2的正半周期间。

传统的直流调速技术因体积大故障率高而应用受限。20世纪60年代以后，电力电子器件普遍应用了晶闸管及其升级产品。但其调速性能远远无法满足需要。1968年以丹佛斯为代表的高技术企业开始批量化生产变频器，开启了变频器工业化的新时代。20世纪70年代开始，脉宽调制变压变频(PWM－VVVF)调速的研究得到突破，20世纪80年代以后微处理器技术的完善使得各种优化算法得以容易的实现。20世纪80年代中后期，美、日、德、英等发达国家的VVVF变频器技术实用化，商品投入市场，得到了广泛应用。早的变频器可能是日本人买了英国专利研制的。不过美国和德国凭借电子元件生产和电子技术的优势，高端产品迅速抢占市场。步入21世纪后。

吸合电流吸合电流是指继电器能够产生吸合动作的电流。在正常使用时，给定的电流必须略大于吸合电流，这样继电器才能稳定地工作。而对于线圈所加的工作电压，一般不要超过额定工作电压的1.5倍，否则会产生较大的电流而把线圈烧毁。释放电流释放电流是指继电器产生释放动作的电流。当继电器吸合状态的电流减小到一定程度时，继电器就会恢复到未通电的释放状态。这时的电流远远小于吸合电流。电压电流触点切换电压和电流是指继电器允许加载的电压和电流。它决定了继电器能控制电压和电流的大小，使用时不能超过此值，否则很容易损坏继电器的触点。触点性能a．动合主触点性能动合主触点在电压不大于250V时，能接通直流或交流5A，但是断开它所接通的电路。

ZVS），或是通过开关管的电流为零，即零电流开关（Zero-Current·Switching，ZCS）。这种软开关方式可以显着地减小开关损耗，以及开关过程中激起的振荡，使开关频率可以大幅度提高，为转换器的小型化和模块化创造了条件。功率场效应管（MOSFET）是应用较多的开关器件，它有较高的开关速度，但同时也有较大的寄生电容。它关断时，在外电压的作用下，其寄生电容充满电，如果在其开通前不将这一部分电荷放掉，则将消耗于器件内部，这就是容性开通损耗。为了减小或消除这种损耗，功率场效应管宜采用零电压开通方式（ZVS）。绝缘栅双极性晶体管（InsulatedGateBipolartansistor，IGBT）是一种复合开关器件。
