A New Single-Phase Single Source Nine Level Boost Inverter Topology

This paper proposed a new single-phase single stage single source nine-level boost inverter topology with self-voltage balancing along with the reduce switch count. The proposed topology is aimed to design for the renewable energy sources interfacing to the loads, which require higher voltage magnitudes. The proposed topology gives twice voltage booting feature without using any dc-dc converter. The topology proposed in this paper uses a single dc voltage source with two capacitors to generate a nine-level output voltage waveform. Nearest level control modulation technique has been used for the generation of gate pulse for the different switches used in the proposed structure. Different simulation results have been provided using PLECS software, and these simulation results have been verified using the experimental results obtained from a laboratory prototype.
