A Single-Source-Based 13-Level Switched Capacitor Multilevel Inverter with Reduced Components

This research study proposes a single-source-based 13-level switched capacitor multilevel inverter (SCMLI) with self-capacitor voltage balancing and self-output voltage boosting capabilities. The proposed SCMLI needs fewer switching devices, gate driver circuits, and power diodes than comparable single-source-based 13 level SCMLIs. The developed SCMLI’s cost-effectiveness compared to others is significantly increased by the reduced component required. Compared to other SCMLIs, the developed SCMLI provides the lowest cost function per level. The circuit setup, working modes, switch stress analysis, and optimum capacitor selection method for the developed SCMLI are all thoroughly described in the paper. A simulation analysis using MATLAB/Simulink and a practical study using a hardware prototype of the proposed SCMLI have verified its performances. It has been found that the developed SCMLI can realize 13 output voltage steps with 3 times higher voltage than input source and performs well under a variety of load circumstances, including resistive, inductive, and dynamic load change conditions.
