We have already discussed in detail about the working of BJT and the working of MOSFET and how they are used in circuits. But, both these components had some limitations to be used in very high current applications. So, we moved another popular power electronic switching device called the IGBT. You can think of IGBT as a fusion between BJT and MOSFET, these components have the input characteristics of a BJT and output characteristics of a MOSFET.  In this article, we get familiar with the basics of IGBT, how they work, and how to use them in your circuit designs. 

 IGBT is the short form of Insulated Gate Bipolar Transistor. It is a three-terminal semiconductor switching device that can be used for fast switching with high efficiency in many types of electronic devices. These devices are mostly used in amplifiers for switching/processing complex wave patters with pulse width modulation (PWM). The typical symbol of IGBT  along with its image is shown below.As mentioned earlier an IGBT is a fusion between a BJT and MOSFET.  The symbol of the IGBT also represents the same, as you can see the input side represents a MOSFET with a Gate terminal and the output side represents a BJT with Collector and Emitter. The Collector and the Emitter are the conduction terminals and the gate is the control terminal with which the switching operation is controlled.

 IGBT can be constructed with the equivalent circuit that consists of two transistors and MOSFET, as the IGBT posses the output of the below combination of the PNP transistor, NPN transistor, and MOSFET. IGBT combines the low saturation voltage of a transistor with the high input impedance and switching speed of a MOSFET. The outcome obtained from this combination delivers the output switching and conduction characteristics of a bipolar transistor, but the voltage is controlled like a MOSFET.Since IGBT is the combination of MOSFET and BJT they are also called by different names. The different names of IGBT are  Insulated Gate Transistor( IGT), Metal Oxide Insulated Gate Transistor (MOSIGT), Gain Modulated Field Effect Transistor (GEMFET), Conductively Modulated Field Effect Transistor (COMFET).IGBT has three terminals attached to three different metal layers, the metal layer of the gate terminal is insulated from the semiconductors by a layer of silicon dioxide (SIO2).  IGBT is constructed with 4 layers of semiconductor sandwiched together. The layer closer to the collector is the p+ substrate layer above that is the n- layer, another p layer is kept closer to the emitter and inside the p layer, we have the n+ layers. The junction between the p+ layer and n- layer is called the junction J2 and the junction between the n- layer and the p layer is called the junction J1. The structure of IGBT is shown in the figure below.To understand the working of the IGBT, consider a voltage source VG connected positively to the Gate terminal with respect to the Emitter. Consider other voltage source VCC connected across The Emitter and the Collector, where Collector is kept positive with respect to the Emitter. Due to the voltage source VCC the junction J1 will be forward-biased whereas the junction J2 will be reverse biased. Since J2 is in reverse bias there will not be any current flow inside the IGBT(from collector to emitter).

 

Initially, consider that there is no voltage applied to the Gate terminal, at this stage the IGBT will be in a non-conductive state. Now if we increase the applied gate voltage, due to the capacitance effect on the SiO2 layer the negative ions will get accumulated on the upper side of the layer and the positive ions will get accumulated on the lower side of the SiO2 layer. This will cause the insertion of negative charge carriers in the p region,  higher the applied voltage VG greater the insertion of negatively charged carriers. This will lead to a formation of the channel between the J2 junction which allows the flow of current from collector to emitter. The flow of current is represented as the current path in the picture, when the applied Gate voltage VG increases the amount of current flow from the collector to the emitter also increases.The IGBT is classified as two types based on the n+ buffer layer, the IGBTs that are having the n+ buffer layer is called the Punch through IGBT (PT-IGBT), the IGBTs that does not have an n+ buffer layer are called the Non-Punch Through- IGBT (NPT- IGBT).

 

Based on their characteristics the NPT- IGBT, and PT-IGBT are named as symmetrical and nonsymmetrical IGBTs. The symmetrical IGBTs are the ones that have equal forward and reverse breakdown voltage. The asymmetric IGBTs are the ones that have a reverse breakdown voltage less than the forward breakdown voltage. The symmetrical IGBTs are mostly used in AC circuits, whereas the asymmetrical IGBTs are mostly used in DC circuits because they don’t need to support voltage in the reverse direction.The collector of the PNP transistor is connected to the NPN transistor through a JFET, the JFET connects the collector of the PNP transistor and the base of the PNP transistor. These transistors are arranged in a way to form a parasitic thyristor set up to create a negative feedback loop. The Resistor RB is placed to short the base and emitter terminals of the NPN transistor to ensure that the thyristor doesn’t latch-up which leads to the latch-up of the IGBT. The JFET used here will signify the structure of current between any two IGBT cells and allows the MOSFET and supports most of the voltage.

可编程序控制器的英文为Programmable Controller，在二十世纪70-80年代0直简称为PC。由于到90年代，个人计算机发展起来，也简称为PC;加之可编程序的概念所涵盖的范围太大，所以美国AB公司将可编程序控制器定名为可编程序逻辑控制器(PLC-Programmable Logic Controller)，为了方便，仍简称PLC为可编程序控制器。有人把可编程序控制器组成的系统称为PCS可编程序控制系统，强调可编程序控制器生产厂商向人们提供的已是完整的系统了。

PLC的发展历史
1968年美国GM(通用汽车)公司提出取代继电器控制装置的要求，二年美国数字公司研制出了代可编程序控制器，满足了GM公司装配线的要求。随着集成电路技术和计算机技术的发展，现在已有五代PLC产品了。
在以改变几何形状和机械性能为特征的制造工业和以物理变化和化学变化将原料转化成产品为特征的过程工业中，除了以连续量为主的反馈控制外，特别在制造工业中存在了大量的开关量为主的开环的顺序控制，它按照逻辑条件进行顺序动作号按照时序动作;另外还有与顺序、时序无关的按照逻辑关系进行连锁保护动作的控制;以及大量的开关量、脉冲量、计时、计数器、模拟量的越限报警等状态量为主的—离散量的数据采集监视。由于这些控制和监视的要求，所以PLC发展成了取代继电器线路和进行顺序控制为主的产品。在多年的生产实践中，逐渐形成了PLC、DCS与IPC三足鼎立之势，还有其它的单回路智能式调节器等在市场上占0定的百分比。

Switching Characteristics of IGBT

The IGBT is a Voltage controlled device, hence it only requires a small voltage to the gate to stay in the conduction state. And since these are unidirectional devices,  they can only switch current in the forward direction which is from collector to emitter. A typical switching circuit of IGBT is shown below, the gate volt VG is applied to the gate pin to switch a motor (M) from a supply voltage V+. The resistor Rs is roughly used to limit the current through the motor.The input characterictcs of IGBT can be understood from the graph below. Initially, when no voltage is applied to the gate pin the IGBT is in turn off condition and no current flows through the collector pin. When the voltage applied to the gate pin exceeds the threshold voltage, the IGBT starts conducting and the collector current IG starts to flow between the collector and emitter terminals. The collector current increases with respect to the gate voltage as shown in the graph below.The output characteristics of IGBT have three stages, initially, when the Gate Voltage VGE is zero the device is in the off state, this is called the cutoff region. When VGE is increased and if it is less than the threshold voltage then there will be a small leakage current flowing through the device, but the device will still be in the cutoff region. When the VGE is increased beyond the threshold voltage the device goes into the active region and the current starts flowing through the device. The flow of current will increases with an increase in the voltage VGE as shown in the graph above.IGBTs are used in various applications such as AC and DC motor drives, Unregulated Power Supply (UPS), Switch Mode Power Supplies (SMPS), traction motor control and induction heating, inverters, used to combine an isolated-gate FET for the control input and a bipolar power transistor as a switch in a single device, etc.GBTs are available in different kinds of packages with different names from different companies. For example, Infineon Technologies offer Thru-Hole type and Surface mount packages. The Thru-hole type package includes TO-262, TO-251, TO-273, TO-274, TO-220, TO-220-3 FP, TO-247, TO-247AD. The surface-mount package includes TO-263, TO-252.贝加莱是0个总部坐落奥地利并具有遍及0球分支机构的立异驱动型企业，2017年7月，贝加莱成为ABB集团的0个事务单元。作为0球必威西甲范畴的0导者，贝加莱交融了前沿技能与先进的工程才能，为各个工业客户供给机器与工厂、运动操控、HMI以及集成安0技能的完好解决计划。贝加莱坚持继续的立异精力，为客户供给更为简化以及超出预期的必威西甲范畴前沿技能与计划贝加莱使机器制作商可以树立与工厂及现场机械的继续衔接。经过LogTunnel，可将世界各地机器中的数据存储在中心方位。功用方面出现任何不正常状况都可以及早发现，然后有助于坚持0大可用性贝加莱已更新其APROL必威西甲操控体系的生命周期办理战略。除了0般的0要版别和安0补丁之外，贝加莱还将供给每月的操作体系更新。现在，APROL在施行现代网络安0战略方面比以往任何时候预备得都更充沛由贝加莱支撑的团队在活动开始时收到使命，他们有必要在三地利间里将概念转变为功用样机。为了协助项目顺畅施行，贝加莱向学生供给了软件和硬件，肯普滕运用技能大学自行开发了机器人，并将其带到活动现场。肖维荣博士，作为贝加莱大中华区的0导者和必威西甲职业开展的亲历者，凭仗耕耘25年机械范畴的实践，在这个特别的时间里，十分乐意与业界朋友们0同共享他对整个工业开展头绪整理、企业竞争力刻画、人才培养等论题打开沟通。霍尼韦尔HONEYWELL CC-PCNT01模块的C300控制器为分布式控制系统(DCS)提供了强大和鲁棒的控制。霍尼韦尔HONEYWELL  CC-PCNT01模块C300是运行霍尼韦尔现场验证的确定性控制执行环境(CEE)核心软件的0个节点。霍尼韦尔HONEYWELL CC-PCNT01模块  CEE软件提供了0个优越的控制执行和调度环境。霍尼韦尔HONEYWELL  CC-PCNT01模块每个控制器节点的控制策略是通过0个通用的控制生成器配置和加载的，这是0个简单而实用的工程工具。除了预建功能块和算法的标准和健壮库，霍尼韦尔HONEYWELL  CC-PCNT01模块C300控制器还支持自定义算法块(CAB)霍尼韦尔HONEYWELL CC-PCNT01模块自定义算法块在用途和结构上与Control  Builder分发的标准功能块相似。然而，cab有用户定义的算法和数据结构，允许根据特定的需求开发定制的策略。霍尼韦尔HONEYWELL  CC-PCNT01模块C300控制器与系列8  I/O共享其硬件设计，提供了0种创新的设计，减少了占地面积和安装和维护成本。C300控制器模块安装在C300输入输出终端组件(IOTA)上。C300  IOTA仅包含被动设备，如FTE地址交换机.0般的进行数据远传，可以使用4G智能网关设备，实现针对不同的协议，不同接口设备的数据的远传，很多这样的企业都有自己的云平台，客户可以借此云平台实现远程维护，降低维护成本。 在终端自动化中，经常会使用到机器人应用，确切来说，是在处理硬纸板码垛时，或在涉及二级包装和托盘热封时。此时，人身安0的防护尤为重要，0般通过防护装置来保障安0。在维护或出现故障时，必须能够快速安0地让机器恢复运行，以0大限度地减少非生产性停机。
