Abstract :
A three-level GTO inverter topology is presented. This new power circuit includes many advantages compared with the conventional three-level GTO inverter. The main advantages are snubberless and good device utilization by using a dual quasi-resonant DC-link which guarantees the complete zero voltage switching of the inverter GTOs. This three-level GTO inverter can be operated with lower switching loss at higher switching frequency with complete zero voltage inverter switching
