Abstract: Single-Phase AC-DC-AC converters are employed in vast of applications such as UPS Systems, Motor Drives, Yaw Drives, Traction and Micro Grids. This paper introduces an incipient topology for multilevel inverter based Single-Phase AC-DC-AC converter for different types of loads. The suggested converter consists of two phases; a full bridge rectifier that converts AC supply to DC supply and a multilevel inverter that converts DC supply to AC supply cascaded into a rectifier. For the proposed system, the multilevel inverter is chosen as it raises the voltage output level and thus diminishes the Total Harmonic Distortion (THD). The converter suggested here effectively reduces the harmonics in the output voltage and using Multilevel Inverter, reduces THD in the AC-DC-AC converter. The simulation outcomes are acquired from MATLAB® Simulink platform and a hardware prototype of the inverter is done.
