Switched Capacitor-Multi level Inverter (SC-MLI) is appropriate for PV, Wind and sustainable energy applications because of the need for less no. of dc sources. This article presented the SC-MLI topology which consists of only two dc supplies and switches several capacitors in series for maximizing the no. of levels. The suggested inverter is self-balanced and offers reduced voltage stress on switches, resulting in lower switching losses. Moreover, this topology offers benefits over most known MLIs, such as less passives and switches, higher boosting capability, and less expensive. The efficacy of the suggested topology is tested in off grid mode for various operating conditions as well as grid-connected mode with Model Predictive Control for current control. This inverter was simulated in the Simulink section of the MATLAB.

摘要

Switched Capacitor-Multi level Inverter (SC-MLI) is appropriate for PV, Wind and sustainable energy applications because of the need for less no. of dc sources. This article presented the SC-MLI topology which consists of only two dc supplies and switches several capacitors in series for maximizing the no. of levels. The suggested inverter is self-balanced and offers reduced voltage stress on switches, resulting in lower switching losses. Moreover, this topology offers benefits over most known MLIs, such as less passives and switches, higher boosting capability, and less expensive. The efficacy of the suggested topology is tested in off grid mode for various operating conditions as well as grid-connected mode with Model Predictive Control for current control. This inverter was simulated in the Simulink section of the MATLAB.
