  Recent research on multilevel inverters shows exciting properties, including
the potential to generate multiple output voltages and integrated voltage
boosting. However, most presented inverter topologies have a restricted number
of output voltage levels and limited output voltage boosting ratio. In
addition, balancing the voltage of capacitors in multilevel converters is very
important and should be considered in the topology or control method. This
paper describes a generalized switched-capacitor circuit topology for
multilevel dc-to-ac inverters that can be developed for the desired output
voltage levels. Also, the maximum ac output voltage can vary from values much
lower than the dc input voltage to several times of it depending on the design
requirement. High-voltage dc input and ac output could be handled using
low-voltage capacitors, which substantially decreases overall cost and volume.
The proposed topology further allows for easy expansion through stackable
circuits for multiple load phases. It has an inherent capacity for balancing
the voltage of capacitors. To validate the feasibility and practicality of this
concept, we provide circuit descriptions, control strategies, design
recommendations, and pertinent simulation findings for the suggested inverter
topology.
