Abstract

Multilevel inverters are vastly used in power systems and “renewable energy sources” (RES) to provide an AC voltage with a low level of harmonic contents. This paper aims to design a 9-level inverter for RES such as photovoltaic (PV), wind turbines, and fuel cells… etc. The proposed inverter is constructed by 12 IGBT switching devices where all of which are powered by 4 DC sources of 81 V without balancing capacitors to make DC voltage 324 V. A Phase disposition (PD), alternative phase opposition disposition (APOD), and POD with a slight phase shift are the methods of modulations that are used to provide a sinusoidal waveform of the output voltage and current. The minimum “Total harmonic distortion” (THD %) of the output voltage of the inverter is 13.68 % and 1.7 % in the cases where there is no filter and with filter conditions respectively. The load voltage is regulated by a PI controller based on the RMS value of the inverter output voltage.
