A Novel Common Neutral Line Thirteen-Level Switched Capacitor Boost Inverter with Inductive load ability

In recent times, researchers have been trying to reduce the number of switches and boost the voltage gain in the multilevel inverter (MLI). It can be accomplished easily in mid-point switched capacitor MLI. However, while doing so, the voltage stress on the semiconductor devices increases significantly, which reduces the inverter’s reliability. In addition, it is unable to reduce the leakage current in solar photovoltaic applications. Therefore, A novel single-source common neutral line thirteen-level switched capacitor boost inverter is proposed in this paper. It has lesser voltage stress on semiconductor devices, a sixfold voltage-boosting ability, and good reliability. Moreover, its common neutral line provides the features of a common grounding, which allows it to be used in solar PV systems, as it reduces leakage current significantly. To operate the proposed inverter, the nearest level control technique has been implemented in MATLAB/Simulink. The results have been analyzed and discussed to show the goodness of the inverter. The comparison analysis has also been included to strengthen the effectiveness of the proposed inverter.
