Grid integration of PV system using Marx multilevel inverter

Abstract

The main aim of this paper is to integrate the solar photovoltaic system to the grid by using Marx multilevel inverter. The Marx multilevel inverter gives several levels of dc voltages to the desirable ac voltage. Theoretically, the number of voltage levels is arbitrarily chosen in Marx multilevel inverter, without using of transformer the output voltage of the inverter can reach high level. In addition, due to the step characteristic, the output voltage can be almost sinusoidal which results decrease the size and cost of the filter. The control modulation method for the grid integration of Marx multilevel inverter has been chosen and implemented. Finally, the topologies are implemented using MATLAB
