A Switched Capacitor Based Inverter Using a DC Source and Lesser Components

A wide range of increased power capability and energy efficiency of renewables and high frequency power delivery systems has been recognised for multi-level inverters (MLI) with no extra hardware circuit used to charge capacitors. The brief description shows a 13L SCI topology with a lower number of switches, capacitors, and a single source. The SC-based 13L inverter increases high voltage gain and self-balanced voltage across capacitors by means of appropriate charging and discharge patterns. Comparative analyses of various types of recent MLI topologies in terms of number of switches, capacitors, diodes, total standing voltage, and cost factor demonstrate the proposed 13L SC-based inverter topology. In addition, MATLAB R2018b software was used to confirm the workability of the proposed 13L SCI with the use of both R and R-L load test conditions. A longer version of this paper is in the works, and it will be sent to the journal with the experiments.
