翻译一下，是关于IGCT的，

IGCT integrated gate commutated thyristor (Intergrated Gate Commutated Thyristors) is a giant power electronics package for the new device power semiconductor devices. IGCT converter in the power, reliability, switching speed, efficiency, cost, size, weight and have made tremendous progress, to power electronic devices has set a new leap forward. IGCT is GTO chips and anti-parallel diodes and gate drive circuit integration with its gate to drive in the external low inductance way to connect with the transistor stability shutdown capability and low-pass thyristor loss of the advantages of the on-stage performance thyristor play-off stage show Crystal the characteristics. IGCT with current, high voltage, high switching frequency, high reliability and compact structure, and low loss characteristics, but have led to the low yield, a good prospect.
