5SHY4045L0006 ABB 可編程邏輯控制器是一種中壓變頻器開發(fā)的用于巨型電力電子成套裝置中的電力半導(dǎo)體開關(guān)器件(集成門極換流晶閘管=門極換流晶閘管+門極單元)。
1997年由ABB公司提出。IGCT使變流裝置在功率、可靠性、開關(guān)速度、效率、成本、重量和體積等方面都取得了巨大進展，給電力電子成套裝置帶來了新的飛躍。
IGCT是將GTO芯片與反并聯(lián)二極管和門極驅(qū)動電路集成在一起，再與其門極驅(qū)動器在外圍以低電感方式連接，結(jié)合了晶體管的穩(wěn)定關(guān)斷能力和晶閘管低通態(tài)損耗的優(yōu)點

5SHY4045L0006 ABB 可編程邏輯控制器梯形邏輯廣泛應(yīng)用于工業(yè)環(huán)境中，用于編程需要對制造過程和操作進行順序控制的PLC。這種編程語言對于編程簡單而關(guān)鍵的系統(tǒng)或者將舊的硬連線系統(tǒng)改造成新的可編程系統(tǒng)非常有用。這種編程語言也大量用于高度復(fù)雜的自動化系統(tǒng)，如電子和汽車工廠。 梯形邏輯背后的想法是，即使沒有編程背景的人員也可以快速編程，因為它利用常規(guī)和熟悉的工程符號進行編程。但是這種優(yōu)勢很快就被否定了，因為PLC的制造商通常也為他們的產(chǎn)品提供梯形邏輯編程系統(tǒng)，這些系統(tǒng)有時不使用與其他制造商的其他型號的PLC相同的符號和約定；事實上，編程系統(tǒng)通常只適用于特定的型號，所以程序不容易移植到其他PLC型號上，或者必須徹底重寫。

5SHY4045L0006 ABB Programmable Logic Controller is a power semiconductor switching device (integrated gate commutated thyristor = gate commutated thyristor + gate unit) developed by medium voltage inverter for use in large power electronics packages.
It was proposed by ABB in 1997. IGCT has made great progress in power, reliability, switching speed, efficiency, cost, weight and volume, and has brought a new leap to power electronic complete sets.
IGCT integrates the GTO chip with the anti-parallel diode and gate driver circuit, and then connects it with the gate driver in a low inductance mode at the periphery, combining the stable turn-off ability of the transistor and the advantages of the low on-state loss of the thyristor
The performance of thyristor is displayed in the on-stage, and the characteristics of transistor are displayed in the off-stage. IGCT has the characteristics of large current, high blocking voltage, high switching frequency, high reliability, compact structure, low on-off loss, etc., and it has low cost and high yield, so it has a good application prospect.

5SHY4045L0006 ABB Programmable Logic Controller Ladder logic is widely used in industrial environments for programming PLCS that require sequential control of manufacturing processes and operations. This programming language is useful for programming simple and critical systems or for retrofitting old hard-wired systems into new programmable systems. This programming language is also used extensively in highly complex automation systems, such as electronics and automotive factories. The idea behind ladder logic is that even people without a programming background can program quickly because it makes use of regular and familiar engineering notation to program. But this advantage was quickly negated because manufacturers of PLCS often also offered ladder logic programming systems for their products, which sometimes did not use the same symbols and conventions as other models of PLCS from other manufacturers; In fact, programming systems are usually only available for specific models, so programs are not easily ported to other PLC models, or must be completely rewritten.
