描述

IGCT使變流裝置在功率、可靠性、開(kāi)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(lái)了新的飛躍。IGCT是將GTO芯片與反并聯(lián)二極管和柵極驅(qū)動(dòng)電路集成在一起，再與其柵極驅(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、電壓高、開(kāi)關(guān)頻率高、可靠性高、結(jié)構(gòu)緊湊、損耗低等特點(diǎn)，而且造成本低，成品率高，有很好的應(yīng)用前景。采用晶閘管技術(shù)的GTO是常用的大功率開(kāi)關(guān)器件，它相對(duì)于采用晶體管技術(shù)的IGBT在截止電壓上有更高的性能，但廣泛應(yīng)用的標(biāo)準(zhǔn)GTO驅(qū)動(dòng)技術(shù)造成不均勻的開(kāi)通和關(guān)斷過(guò)程，需要高成本的dv/dt和di/dt吸收電路和較大功率的柵極驅(qū)動(dòng)單元，因而造成可靠性下降，價(jià)格較高，也不利于串聯(lián)。但是，在大功率MCT技術(shù)尚未成熟以前，IGCT已經(jīng)成為高壓大功率低頻交流器的優(yōu)選方案。

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 their 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, exerting the performance of thyristors during the conduction phase, and presenting transistor characteristics during the turn-off phase. IGCT has the characteristics of high current, high voltage, high switching frequency, high reliability, compact structure, low losses, and low manufacturing cost, high yield, and has good application prospects. GTO using thyristor technology is a commonly used high-power switching device, which has higher performance in cutoff voltage compared to IGBT using transistor technology. However, the widely used standard GTO driving technology causes uneven turn-on and turn-off processes, requiring high cost dv/dt and di/dt absorption circuits and high-power gate driving units, resulting in reduced reliability, high price, and unfavorable series connection. However, before the high-power MCT technology was mature, IGCT had become the preferred solution for high-voltage high-power low-frequency AC converters.
