Abstract

Multi Level Inverters (MLI) are commonly used in high voltage and high power applications due totheir lower filtering requirements. The current project deals with the research and review of cascaded multi-level inverter single-stage switched-capacitor module (S3CM) topology to ensure the optimal inverse voltage over all switches within the voltage of the dc source. The key aim of our research is to study the generation of nine voltage levels with just one dc source and two built-in capacitors.Therefore, when compared with the Single Phase Nine Level Inverter (SPNLI) using a coupled inductor, the number of components has been greatly reduced in this module. In addition, the gain of two is obtained by voltage boosting. By circuit analysis accompanied by various types of pulse techniques, the operation of the proposed topology is validated. The inverter topology of full S3CM bridges allows low current THD factor to be achieved using a simple capacitor instead of complicated LCL filters benefiting Whereas while using the single DC source, it is possible to choose switching angles in such a way to have  output voltage THD as less than 13 percent.
