【Abstract】 According to the demand of basic logical function of integrated gate commutated thyristor (IGCT) gate drive circuit, a novel scheme is presented. Applying electronic design automation and complex programmable logic devices chip technique, a high reliability, single-chip and flexible design is realized. A kind of gate drive circuit adopting hard driven and integrated gate technique is designed,which possesses high switching speed, simple structure, high reliability, and convenience for adding protection and test circuit. The results of emulation indicate that gate current can rapidly reach to 200 A within 2 μs when turn-on and can extract 400 A within 4 μs when turn-off, which satisfies the requirement of switching characteristics of IGCT.更多还原
