A large-capacity inverter using high-power gate turn-off (GTO) thyristors that can be used instead of a cycloconverter in ac drives is presented. With the techniques of multiple configuration and GTO series connection, the inverter capacity is increased effectively. High conversion efficiency is obtained by using low-loss snubber circuits for GTO's. It is confirmed that the low-loss snubber circuits using energy recovery units (ERU's) have good performance in PWM operation. High-energy recovery efficiency is obtained, especially in leading operation (turn-on operation when freewheeling diodes conduct). These snubber circuits have the superior ability for clamping overvoltage at GTO turn-off. The 2750-kVA inverter with low-loss snubber circuits using high-power GTO's is fabricated and evaluated.
