电流⒈ 额定通态电流（IT）即最大稳定工作电流，俗称电流。常用可控硅的IT一般为一安到几十安。耐压⒉反向重复峰值电压（VRRM）或断态重复峰值电压（VDRM），俗称耐压。常用可控硅的VRRM/VDRM一般为几百伏到一千伏。触发电流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。额定正向平均电流4.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常用可控硅的封装形式有TO-92、TO-126、TO-202AB、TO-220、TO-220ABC、TO-3P、SOT-89、TO-251、TO-252、SOT-23、SOT23-3L
普通晶闸管最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。以最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，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。通过改变控制角α或导通角θ，改变负载上脉冲直流电压的平均值UL，实现了可控整流。1：小功率塑封双向可控硅通常用作声光控灯光系统。额定电流：IA小于2A。2：大；中功率塑封和铁封可控硅通常用作功率型可控调压电路。像可调压输出直流电源等等。3：大功率高频可控硅通常用作工业中；高频熔炼炉等。可控硅从外形上分主要有螺旋式、平板式和平底式三种，螺旋式的应用较多。可控硅有三个电极－－-阳极（A）阴极（C）和控制极（G）。它有管芯是P型导体和N型导体交迭组成的四层结构，共有三个PN结。可控硅和只有一个PN结的硅整流二极度管在结构上迥然不同。可控硅的四层结构和控制极的引用，为其发挥“以小控大”的优异控制特性奠定了基础。在应用可控硅时，只要在控制极加上很小的电流或电压，就能控制很大的阳极电流或电压。电流容量达几百安培以至上千安培的可控硅元件。一般把5安培以下的可控硅叫小功率可控硅，50安培以上的可控硅叫大功率可控硅。可控硅为什么其有“以小控大”的可控性呢？下面我们用图表-27来简单分析可控硅的工作原理。
首先，可以把从阴极向上数的第一、二、三层看面是一只NPN型号晶体管，而二、三四层组成另一只PNP型晶体管。其中第二、第三层为两管交迭共用。当在阳极和阴极之间加上一个正向电压Ea，又在控制极G和阴极C之间（相当BG1的基一射间）输入一个正的触发信号，BG1将产生基极电流Ib1，经放大，BG1将有一个放大了β1倍的集电极电流IC1。因为BG1集电极与BG2基极相连，IC1又是BG2的基极电流Ib2。BG2又把比Ib2（Ib1）放大了β2的集电极电流IC2送回BG1的基极放大。如此循环放大，直到BG1、BG2完全导通。实际这一过程是“一触即发”的过程，对可控硅来说，触发信号加入控制极，可控硅立即导通。导通的时间主要决定于可控硅的性能。可控硅一经触发导通后，由于循环反馈的原因，流入BG1基极的电流已不只是初始的Ib1，而是经过BG1、BG2放大后的电流（β1*β2*Ib1）这一电流远大于Ib1，足以保持BG1的持续导通。此时触发信号即使消失，可控硅仍保持导通状态只有断开电源Ea或降低Ea，使BG1、BG2中的集电极电流小于维持导通的最小值时，可控硅方可关断。当然，如果Ea极性反接，BG1、BG2由于受到反向电压作用将处于截止状态。这时，即使输入触发信号，可控硅也不能工作。反过来，Ea接成正向，而触动发信号是负的，可控硅也不能导通。另外，如果不加触发信号，而正向阳极电压大到超过一定值时，可控硅也会导通，但已属于非正常工作情况了。可控硅这种通过触发信号（小的触发电流）来控制导通（可控硅中通过大电流）的可控特性，正是它区别于普通硅整流二极管的重要特征。普通可控硅的三个电极可以用万用表欧姆挡R×100挡位来测。大家知道，晶闸管G、K之间是一个PN结（a），相当于一个二极管，G为正极、K为负极，所以，按照测试二极管的方法，找出三个极中的两个极，测它的正、反向电阻，电阻小时，万用表黑表笔接的是控制极G，可以用刚才演示用的示教板电路。接通电源开关S，按一下按钮开关SB，灯泡发光就是好的，不发光就是坏的。鉴别可控硅三个极的方法很简单，根据P-N结的原理，只要用万用表测量一下三个极之间的电阻值就可以。阳极与阴极之间的正向和反向电阻在几百千欧以上，阳极和控制极之间的正向和反向电阻在几百千欧以上（它们之间有两个P-N结，而且方向相反，因此阳极和控制极正反向都不通）。
控制极与阴极之间是一个P-N结，因此它的正向电阻大约在几欧-几百欧的范围，反向电阻比正向电阻要大。可是控制极二极管特性是不太理想的，反向不是完全呈阻断状态的，可以有比较大的电流通过，因此，有时测得控制极反向电阻比较小，并不能说明控制极特性不好。另外，在测量控制极正反向电阻时，万用表应放在R*10或R*1挡，防止电压过高控制极反向击穿。若测得元件阴阳极正反向已短路，或阳极与控制极短路，或控制极与阴极反向短路，或控制极与阴极断路，说明元件已损坏。
可控硅是可控硅整流元件的简称，是一种具有三个PN结的四层结构的大功率半导体器件。实际上，可控硅的功用不仅是整流，它还可以用作无触点开关以快速接通或切断电路，实现将直流电变成交流电的逆变，将一种频率的交流电变成另一种频率的交流电，等等。可控硅和其它半导体器件一样，其有体积小、效率高、稳定性好、工作可靠等优点。它的出现，使半导体技术从弱电领域进入了强电领域，成为工业、农业、交通运输、军事科研以至商业、民用电器等方面争相采用的元件。

Passing high currents through the glass produces direct heating in the resistance presented by the glass, named boosting. This heating is beneficial as it heats the‘colder’ bottom glass in the furnace. This heated bottom glass rises towards the tophas a stirring effect which helps with melting, heat transfertemperature homogenisation. Boosting is often used to meet periodic fluctuations in production demand or to support the pull rate of a furnace at the end of its operating life. Boosting may also help to reduce NOx emissions. In this application the EPower Controller is controlling the power injected by the electrodes in the molten glass while controlling the true power or the current (the power injected is self compensated by the glass temperature) Controlled convection currents to promote homogeneity Accurate true power or electrodes current control Digital communication allowing process parameters to be monitored by a supervisor: current, voltage, poweralarms Electrodes Molten glass Three phase power supply T2550 Input/output control Eycon™ Visual Supervisor Vacuum furnace control Energy control Efficiency optimization EPower Controller Control Modularity Energy information Several switching modes iTools software configuration Digital communications Vacuum device Digital communication COMPOSITE MATERIAL In composite material production polymerisation is made in an autoclave at very high temperature. EPower Controller controls heating by providing: Detection of total and/or partial load failure Optimization of the distribution of heating control in the different areas providing real cost savings Standard communications for process controlmonitoring on HMI Down time reduction due to the modular design Policeman/Remote display Heater element control Power repartition in heating elements providing energy saving Alarm strategy Digital communication allowing supervisory control Use Predictive Load Management across multiple furnaces to reduce energy costs PLM PLM PLM Predictive Load Management Melting is one of the first steps in the ‘float’ process’. At this stage glass is in liquid state in a molten furnace at around 1550°C. Roof heating is made by silicon carbide heaters. EPower Controller controllers provide all the solutions to the multizone control of this specific heater elements. Ageing compensation of the silicon carbide heaters with power control Power distribution control in the heater elements providing cost savings: suppression of inrush current for a better energy managementa minimum stress on the power transformers Digital communication with standard protocols for an efficient process monitoring Use Predictive Load Management across the glass plant to reduce energy costs www.eurotherm.com/ E Power SEMICONDUCTOR MANUFACTURING Silicon was discovered in 1823 and is used in the manufacture of today''s semiconductors. Semiconductors need a silicon of a very high purity and, therefore, the silicon is transformed by successive stages (crystal growing, epitaxy) that need very slowaccurate heating. The EPower Controller will provide many solutions to this specific and expensive process: Precisesteady control of the heater elements Advancedconfigurable strategy enables the EPower Controller to adapt to the load state Secure your process utilising a comprehensive alarm strategyby transferring process information to a supervisor CONTINUOUS ANNEALING FURNACE After castingmilling, metals are passed through an annealing furnace in order to increase ductilityreduce brittleness. In the case of a continuous metal sheet, this is a multi-zone furnace consuming several Megawatts of power. Each zone consists of one or multiple thermocouples feeding the process variable (PV) into a temperature controller, Programmable Automation Controller (T2550 PAC) or PLC. The control device then calculates the required power input to meet the process set point (SP),sends this to the Power Controller via digital comms or via an analogue signal. The Power Controller then fires the element, either directly or via a transformer depending on the element specifications. Two-leg, true three phase control or 4 x single phase control available Load Sequencing - integral firing sequence control optimises instantaneous energy consumption across all zones Load Shedding - Predictive Load Management peak energy demand algorithm enables power smoothing to reduce peak demand Communication of PV, SPprocess data Remote configuration via comms or user interface TIN BATH FURNACE IN FLOAT MANUFACTURING Three phase power supply Multizone control Molten glass Multizone heating Roof heating with silicon carbide elements Supervisor Slave Master Network Multiple Slaves (1 per Zone) Zone 1 Zone n Continuous Annealing Furnace Transformer Transformer Molten tin PLM PLM PLM Predictive Load Management PLM PLM PLM Predictive Load Management With EPower Controllers you are not only buying one of the best power controllers in the world, you are supported by a global network of application and control specialists from Eurotherm.
