A Novel Cascade 11 Level Inverter Design

Recently, works on the development of equipment in the field of power electronics has been increasing day by day. Inverter design is one of the outstanding issues in the field of power electronics. One of the most important of these studies has been the multi-level inverter topology. Because of their working ability in high power and high efficiency in alternative energy sources, multi-level inverters are preferred. Multilevel inverters have the advantages of lower harmonic on output voltage, lower switching frequency and higher efficiency than conventional inverter designs. In this study, 11 level inverter design is given. The parts forming the inverter structure, the switching method and working principle are explained. The method used to calculate the switching angle and the resulting formulas are presented. Experimental studies were carried out in the Matlab 2017b simulation of multilevel inverter. The designed inverter produces low harmonic output voltage and reduces the dv / dt stress stress on the switching elements. The obtained results can be used in real time applications.
