Abstract
In this paper a new single DC-source switched capacitor Nine-level inverter based on flyback DC-DC converter is presented. The proposed topology reduces the number of switches, diodes and required independent DC-sources. In this topology, a single DC source is used to produce 9-level output voltage waveform. So that, it is suitable for renewable photovoltaic energy systems. Since, in this topology a DC-DC flyback converter is applied so three isolated DC voltage are generated to supply the proposed switched capacitor inverter. There is no need to any complicate control methods for adjusting capacitor voltage around constant values. In order to highlight the advantages of the proposed topology, it has been compared with some other presented topologies in last years. The simulation results of 9-level inverter are obtained by PSCAD software to verify the accurate performance of the proposed multilevel inverter.
