【功能描述】

5SHX1445H0002 ABB 晶體閘流管。晶體閘流管(Thyristor) 又稱作可控硅整流器，曾被簡稱為可控硅，1957年美國通用電器公司開發(fā)出世界上第一晶閘管產(chǎn)品，并于1958年使其商業(yè)化。

5SHX1445H0002 ABB 晶體閘流管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新型電力半導體開關器件(集成門極換流晶閘管=門極換流晶聞管+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。

5SHX1445H0002 ABB 晶體閘流管1GCT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，結合了晶體管的穩(wěn)定關斷力和晶閘管低通態(tài)損拜的優(yōu)點，在導通階段發(fā)揮晶閘管的性能，關斷階段呈現(xiàn)晶體管的特性。GCT具有電流大、陽新電樂高關頻率高、可靠性高、結構緊湊、低導通損耗等特點，而目造成本低，成品率高，有很好的應用前景。已用于電力系統(tǒng)電網(wǎng)裝置(100MVA)和的中功率工業(yè)驅(qū)動裝置 (5MW)1GCT在中壓變頻器領域內(nèi)成功的應用了11年的時間(到09年為止)，5SHX1445H0002 ABB 晶體閘流管由于IGCT的高速開關能力無需緩沖電路，因而所需的功率元件數(shù)目更少，運行的可靠性大大增高

【英文介紹】

5SHX1445H0002 ABB thyristor. Thyristor (Thyristor), also known as thyristor rectifier, was once referred to as thyristor, in 1957 the United States General Electric Company developed the world's first thyristor products, and commercialized it in 1958.

The 5SHX1445H0002 ABB thyristor is a new type of power semiconductor switching device (integrated gate converter thyristor = gate converter transistor + gate unit) developed by medium voltage frequency converter for use in large power electronics sets. 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.

5SHX1445H0002 ABB thyristor 1GCT integrates the GTO chip with the anti-parallel diode and gate drive circuit, and then connects it with the gate driver in a low inductance mode at the periphery, combining the stable switching force of the transistor and the advantages of the low on-state loss of the thyristor to give full play to the performance of the thyristor in the on-stage. The off phase presents the characteristics of the transistor. GCT has the characteristics of high current, high turn-off frequency, high reliability, compact structure, low on-off loss, and low cost, high yield, so it has a good application prospect. Has been used in power systems for power grid devices (100MVA) and medium power industrial drives (5MW)1GCT in the field of medium voltage inverter successful application for 11 years (up to 2009), 5SHX1445H0002 ABB thyristor due to IGCT high speed switching capability without buffer circuit, Therefore, the number of power components required is less, and the reliability of operation is greatly increased
