Abstract: To fulfill the challenging demands of the growing grid, new concepts of the inverters are needed. In this project a reduced switch modular inverter design is detailed. A reduced switch modular inverter design is presented for a modern power system which inputs power from both AC and DC Renewable Sources. The modular inverter is the combination of both three phase inverter and three phase inverter with the neutral point and it supports both symmetrical and asymmetrical loads. Power Electronics Inverter is the key component to couple the two different renewable energy sources such like solar and wind. The converter is the combination of Cuk – SEPIC converters, the input from the source can be either buck or boost or stabilized at a particular value, the inductor in those converters provides the function filter reducing harmonics.
