Investigation of Switched Capacitor Multi Level Inverter Topology for Different Voltage Levels

This paper focuses on the switched-capacitor converter configurations for wide ranges of applications, which have numerous stages which are designed for different voltage levels. A single-phase multilevel boost inverter topology configuration with fifteen levels and nineteen levels are discussed with same switching circuit. The capacitors are connected in series-parallel configuration to generate an output voltage more than input voltage. The same topology can be used for dual conversion configurations like DC-DC and DC-AC by adding a ground terminal at load point.
