描述

IGCT集成門極換流晶閘管(Intergrated Gate Commutated Thyristors)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新型電力半導(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(jìn)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(dòng)電路集成在一起，再與其門極驅(qū)動(dòng)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(diǎn)，在導(dǎo)通階段發(fā)揮晶閘管的性能，關(guān)斷階段呈現(xiàn)晶體管的特性。IGCT具有電流大、阻斷電壓高、開關(guān)頻率高、可靠性高、結(jié)構(gòu)緊湊、低導(dǎo)通損耗等特點(diǎn)，而且造成本低，成品率高，有很好的應(yīng)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(dòng)裝置（5MW）IGCT在中壓變頻器領(lǐng)域內(nèi)成功的應(yīng)用了11年的時(shí)間（到09年為止），由于IGCT的高速開關(guān)能力無需緩沖電路，因而所需的功率元件數(shù)目更少，運(yùn)行的可靠性大大增高。

IGCT Integrated Gate Commutated Thyristors are a new type of power semiconductor switching device developed for medium voltage inverters and used in giant power electronic complete sets (integrated gate commutated thyristors=gate commutated thyristors+gate units). Proposed by ABB in 1997. IGCT has made significant progress in power, reliability, switching speed, efficiency, cost, weight, and volume of converter devices, bringing a new leap to power electronic complete sets of devices. IGCT integrates GTO chips with anti parallel diodes and gate drive circuits, and then connects them with gate drivers in a low inductance manner on the periphery. It combines the stable turn-off ability of transistors and the advantages of low on state losses of thyristors, and utilizes the performance of thyristors during the conduction phase. The turn-off phase exhibits the characteristics of transistors. IGCT has the characteristics of high current, high blocking voltage, high switching frequency, high reliability, compact structure, low conduction loss, and low manufacturing cost, high yield, and has good application prospects. The IGCT, which has been used in power system power grid devices (100MVA) and medium power industrial drive devices (5MW), has been successfully applied in the field of medium voltage frequency converters for 11 years (until 2009). Due to the high-speed switching ability of IGCT without the need for buffer circuits, the required number of power components is fewer, and the reliability of operation is greatly improved.
