Abstract IGCT is a novel power electronic device for high-power application, and the switch control of it must rely on integrated gate drive circuit. Studying on the working principle of IGCT, the paper focuses on the drive technology of IGCT, and the key problems of IGCT switch control which involve hard drive and gate commutation are analyzed. The paper completes the design of drive circuit for 4000A/4500V asymmetric integrated gate commutated thyristor. Meanwhile, experiments for testing the drive technology and circuit are also taken, and results show that the technology can satisfy the driving requirements of 4000A/4500V series IGCT.
