Abstract

For many industrial applications, a voltage boost neutral point clamped (NPC) multilevel inverter is a preferred choice due to its advantages such as low cost, light weight and small in size as compared to a conventional inverter. As this inverter has the boosting property which makes it more suitable for low and medium power renewable energy system. The voltage boost multilevel Z-source inverter and quasi-Z-source inverter have been proposed for dc to ac power conversion with improved power quality. Multilevel ZSI and quasi-ZSI (QZSI) uses more number of passive components in the intermediate impedance network, which increases the system size and weight. So here in this proposed voltage boost neutral-point clamped multilevel (three-level) inverter with LC impedance network uses comparatively less number of passive components and only single dc source required, at the same time it provides all the advantages of multilevel ZSI/QZSI. This proposed inverter has the ability to boost the input dc voltage and provide required three level ac output voltage in a single stage using a shoot through state. Modulation technique adopted for the proposed inverter is unipolar pulse width modulation (PWM) technique to investigate its performance. The prototype has been made and tested using Simulink and dSPACE R&D control board. The results analysis has been done using MATLAB/Simulink software package.
