چکیده

In this brief presents, first a basic structure of 15-level single-phase inverter is presented. The proposed topology works asymmetrically and is capable of producing positive and negative voltage levels at the output. Then, to produce more output voltage levels, the basic structure is expanded and a cascaded multi-level structure is obtained. The new structure is analyzed and compared with several structures in terms of the number of power electronic components used. The result of the comparison shows that the proposed structure uses less power electronic components and is more cost-effective compared to others. Considering the state of the switches and depends on the application, it is possible to use the different kinds of intelligent control methods. Finally, to prove the results, the 15-level inverters is simulated in PSCAD/EMTDC software program.
