In this paper, a simplified space–vector pulse width modulation technique for multilevel inverters is proposed. This method is based on the simplification of the space–vector diagram of a five level inverter into that of a three level inverter. In turn, the three level inverter space vector diagram is simplified into that of two level inverter. Hence, the algorithm of five level space-vector pu...
In this paper a new 5-level single phase symmetrical cascade multi-level inverter is proposed. The proposed topology contains combination of unidirectional and bidirectional power switches based on output voltage level number. The number of power switches and withstanding voltage of powers witches were reduced related to the other topologies. This configuration can be extended to the n-level in...

in order to solve the problem of fuel pollution, the diesel fuel for power generation of marine was abandoned and shore power supply have been proposed at the historic moment. the shore power supply which needs transferring 380v/50hz to 450v/60hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improvi...
A six-level inverter system for an open-end winding induction motor drive is presented in this paper. Multilevel inversion is achieved by feeding an open-end winding induction motor with a 3-level inverter from one end and a 2-level inverter from the other end of the motor. The 3level inverter used in the proposed drive, is realized by cascading two 2-level inverters. The combined inverter syst...
Novel 3-level GTO inverter topology is presented. This new power circuit includes many advantages comparing with the conventional 3-level GTO inverter. The main advantages are snubberless and good device utilization by employing dual quasi-resonant dc-link which guarantees the complete zero voltage switching of the inverter GTO's. This 3-level GTO inverter can be operated with lower switching l...
Dual Two-Level Inverter is an emerging Multilevel Inverter Topology which is implemented by cascading two standard TwoLevel inverters with a six-wire open-end load in between them.
