In this thesis, simulation is shown to get seven level voltage at the output of the grid connected inverter model for real time applications using a Model Predictive Control on the Packed U-Cell inverter which has one isolated DC source and one capacitor as an auxiliary DC link. The MPC is used to regulate the capacitor voltage at the desired magnitude to have seven voltage levels at the output of the inverter. Since grid-connected application is targeted by this application the inverter should be capable of supplying requested amount of active and reactive power at the point of common coupling as well. Multilevel inverter has wide application in high power industries due to the high voltage and low harmonics. Since there are various types of multilevel inverters, due to reduction in number of switches and low switching losses compared to the others type of inverters here Packed U Cell type of multilevel inverter. This is called Packed U cell because of the arrangement of one source and two power switches. It provides energy conversion in high quality using a small number of power semiconductor devices and capacitors in which the production cost is reduced.
