Abstract In media and high voltage large power converter systems, the integrated gate commutated thyristor (IGCT) takes the place of gate turn off thyristor (GTO) due to its outstanding performance. And IGCT-based large power three-level converters are widely used in motor-driving field. In this paper, the development of a set of IGCT-based large power three-level dual-PWM converter is introduced. The PWM rectifier of the converter adopted close-loop control method and SVPWM algorithm to realize the balance of the neutral point voltage. The PWM inverter of the converter adopted SVPWM and SHEPWM modulation strategy. After the converter was developed the experiments were performed. The experiment results show that the converter reaches the design requirement and has excellent performance.
