In this book multilevel inverter (MLI) is proposed. To ensure, the MATLAB Simulink model analysed the seven level, nine level, eleven level and fifteen level. The variation of output voltage and current magnitudes are measured which depend upon the load changes and also the measured Total Harmonic Distortion (THD), that has been compared with the different inverter configurations. The modeling methodology by variation of solar radiation supplies constant input power to the inverter and grid connected system. The Zero Voltage Switching (ZVS) technique is implemented in this described model. The complex system is simplified and it has enhanced the efficiency and improved the electromagnetic interference. The resonant converter designed the combination of two inductors and one capacitor (LLC) which are connected between solar Photovoltaic (PV) source and inverter. sakriti opis
