Digital simulation of renewable energy source controlled EZ-source inverter system

Z-Source inverter for buck-boost energy conversion is implemented using only passive elements with no additional active elements. Therefore Z-Source inverter is less complex. From prospects of Z-Source inverter, an Embedded EZ-Source inverter that can produce the same gain as Z-Source inverter is introduced. This paper contributes the digital simulation of renewable energy source controlled EZ-Source inverter system. Input to the Embedded EZ-Source inverter is obtained from solar cell. The ripple in the output voltage of solar cell is filtered using Z-filter. Pure DC is given to the three-phase inverter. The inverter converts DC in to three-phase balanced AC. The output of the Embedded EZ-Source inverter is used to control the harmonics present in the load. The system is modeled using matlab simulink. Simulation studies are done with induction motor load. The simulation results are presented.
