A Novel Switched Capacitors Based Multilevel Boost Inverter With Single DC Source For Three Phase Applications

This research presents a newest boost inverter with compact switch based on a switched-capacitor approach. The primitive unit is a five-level design that creates the AC output voltage inherently due to the capacitors' self-voltage balancing. Voltage across the capacitor is maintained likely to the input voltage source using a traditional carrier-based sinusoidal modulation approach. The proposed basic unit's N-level structure is also discussed, which has added benefit of increased output voltage rise by a single input. A thorough relation with other topologies of a similar nature has been made. Several results were obtained using a laboratory prototype to assess the feasibility of the suggested main unit and its expansion for seven levels.
