可控硅5SHY3545L0009 IGCT功率模块ABB工控应用行业结构原件

可控硅是P1N1P2N2四层三端结构元件，共有三个PN结，分析原理时，可以把它看作由一个PNP管和一个NPN管所组成，双向可控硅：双向可控硅是一种硅可控整流器件，也称作双向晶闸管。这种器件在电路中能够实现交流电的无触点控制，以小电流控制大电流，具有无火花、动作快、寿命长、可靠性高以及简化电路结构等优点。从外表上看，双向可控硅和普通可控硅很相似，也有三个电极。但是，它除了其中一个电极G仍叫做控制极外，另外两个电极通常却不再叫做阳极和阴极，而统称为主电极Tl和T2。它的符号也和普通可控硅不同，是把两个可控硅反接在一起画成的。5SHY3545L0009的型号，在我国一般用“3CTS”或“KS”表示；国外的资料也有用“TRIAC”来表示的。双向可控硅的规格、型号、外形以及电极引脚排列依生产厂家不同而有所不同，市场上最常见的几种塑封外形结构双向可控硅的外形及电极引脚排列。

IGCT集成门极换流晶闸管(IntergratedGateCommutatedThyristors)，它是将GTO芯片与反并联二极管和门极驱动电路集成在一起，再与其门极驱动器在外围以低电感方式连接而成。也就是门极集成化的GTO（Gate Turn Off）。

IGCT在整流环节中与SCR一脉相承，SCR是Silicon Controlled Rectifier的缩写，是可控硅整流器的简称。可控硅有单向、双向、可关断和光控几种类型。它具有体积小、重量轻、效率高、寿命长、控制方便等优点，被广泛用于可控整流、调压、逆变以及无触点开关等各种自动控制和大功率的电能转换的场合。

Thyristor 5SHY3545L0009 IGCT power module ABB industrial control application industry structure original

Thyristor is a P1N1P2N2 four-layer three-terminal structural element, a total of three PN junction, when analyzing the principle, it can be regarded as composed of a PNP tube and an NPN tube, bidirectional thyristor: bidirectional thyristor is a silicon controllable rectifier device, also known as bidirectional thyristor. This device can realize the contactless control of alternating current in the circuit, and control the large current with small current. It has the advantages of no spark, fast action, long life, high reliability and simplified circuit structure. From the appearance, the bidirectional thyristor is very similar to the ordinary thyristor, and also has three electrodes. However, in addition to one of the electrodes G is still called the control pole, the other two electrodes are usually no longer called the anode and cathode, but collectively referred to as the main electrode Tl and T2. Its symbol is also different from ordinary thyristors, which is drawn by connecting two thyristors together. The model of 5SHY3545L0009 is generally expressed as "3CTS" or "KS" in our country; Foreign data are also represented by "TRIAC". The specification, model, shape and electrode pin arrangement of bidirectional thyristor vary according to the manufacturer. The shape and electrode pin arrangement of bidirectional thyristor are several of the most common plastic sealed shape structures on the market.

IGCT integrated gate converter thyristor (IntergratedGateCommutatedThyristors), it is the decision with the parallel diode chip and gate drive circuit integration in together, with the gate driver in peripheral low inductance mode connection. This is the GTO (Gate Turn Off).

IGCT is in the same vein as SCR in the rectification process, SCR is the abbreviation of Silicon Controlled Rectifier. Thyristors have one-way, two-way, turn-off and light control several types. It has the advantages of small size, light weight, high efficiency, long life, easy control, etc., and is widely used in various automatic control and high-power electric energy conversion occasions such as controlled rectification, voltage regulation, inverter and contactless switch.
