晶閘管(IGCT)模塊，即集成門極換流晶閘管模塊，是一種結(jié)合了晶體管的穩(wěn)定關(guān)斷能力和晶閘管低通態(tài)損耗優(yōu)點的混合型電力半導(dǎo)體器件。IGCT模塊通過將GTO(門極可關(guān)斷晶閘管)芯片與反并聯(lián)二極管和柵極驅(qū)動電路集成在一起，再與其柵極驅(qū)動器在外圍以低電感方式連接，實現(xiàn)了高壓大功率低頻交流器的優(yōu)選方案。IGCT模塊具有電流大、電壓高、開關(guān)頻率高、可靠性高、結(jié)構(gòu)緊湊、損耗低等特點，且成本低、成品率高，具有很好的應(yīng)用前景。
二、工作原理
5SHY3545L0014 3BHB013085R0001 IGCT模塊的工作原理是通過對內(nèi)部PN結(jié)區(qū)域施加正向電壓，將PN結(jié)區(qū)域中的空穴和電子注入到N型感應(yīng)層和P型感應(yīng)層中，形成感應(yīng)電流。同時，在IGCT的門控電極上施加一定的電壓信號，通過控制PN結(jié)區(qū)域中的空穴和電子的復(fù)合和推移，控制整個器件的導(dǎo)通和截止。具體來說，當IGCT的陰極接地、陽極接正電壓時，PN結(jié)區(qū)域中的空穴和電子被注入到N型感應(yīng)層和P型感應(yīng)層中，形成感應(yīng)電流。如果在門極上施加一定的正向電壓，會在PN結(jié)區(qū)域中形成一個正向電場，促使電子和空穴向中間匯集，從而推遲PN結(jié)區(qū)域的耗散時間，使整個器件保持導(dǎo)通狀態(tài)。反之，如果在門極上施加負向電壓或者斷開門極電源，PN結(jié)區(qū)域中的電子和空穴會快速復(fù)合和推移，從而截止整個器件的導(dǎo)通。

Thyristor (IGCT) module, also known as integrated gate commutated thyristor module, is a hybrid power semiconductor device which combines the stable switching ability of transistor with the advantage of low on-state loss of thyristor. The IGCT module integrates the GTO chip with the anti-parallel diode and gate driver circuit, and then connects the gate driver with low inductance at the periphery, which realizes the optimal scheme of high voltage and high power low frequency alternator. IGCT module has the characteristics of high current, high voltage, high switching frequency, high reliability, compact structure, low loss, low cost, high yield, and has a good application prospect.
Second, the working principle
5SHY3545L0014 3BHB013085R0001 IGCT module works by applying a forward voltage to the internal PN junction region, injecting holes and electrons in the PN junction region into the N-type induction layer and P-type induction layer to form an induction current. At the same time, a certain voltage signal is applied to the gated electrode of IGCT to control the on-off and cutoff of the whole device by controlling the recombination and displacement of holes and electrons in the PN junction region. Specifically, when the cathode of IGCT is grounded and the anode is connected with a positive voltage, the holes and electrons in the PN junction region are injected into the N-type induction layer and P-type induction layer to form an induction current. If a certain forward voltage is applied to the gate, a forward electric field will be formed in the PN junction region, prompting electrons and holes to converge to the middle, thus delaying the dissipation time of the PN junction region and keeping the whole device on. Conversely, if a negative voltage is applied to the gate or the gate power supply is disconnected, the electrons and holes in the PN junction region will rapidly recombine and shift, thus cutting off the conduction of the entire device.
