Abstract: There is a disadvantage with a two stage switched capacitor module multi level inverter with the end goal the switches of subsequent level like H connect perseveres which are through higher voltage stress. To determine the issue, in this paper, we proposed a module that guarantees pinnacle reverse voltage among all switches which is limited to dc voltage source for cascaded multilevel inverter. This module is called single stage switched capacitor module (S3 CM). Nine voltage levels are created with just a one dc source, two joined capacitors. Thus, quantity of isolated dc sources was fundamentally decreased contrasted with cascaded H-bridge. What’s more, voltage gain increase by two is accomplished. A similar investigation averse the ongoing methodology uncovers the proposed S3 CM module accomplishes decrease in number of switches. And furthermore switching states of inverter will be controlled by utilizing closed loop PI controller.
