Performance Investigation of Renewable Energy Sources Fed 31-Level MLI for Drive Applications

Due to its ease of maintenance, renewability, low noise level and accessibility, generation of electric power using Photovoltaic (PV) systems has recently become a viable alternative to conventional power generating systems. The output from the PV module is intermittent so that a converter is utilized in improving the supply voltage. In this paper, Flyback converter is employed with high voltage ratios due to its isolation benefit and better efficiency. PWM pulses for converter operation are created from a PWM generator that is powered by carrier signal waves received from Multi carrier PWM. The Multi carrier PWM technique is utilized to produce pulses to the 31-level Multi level inverter switches. The PWM pulses generated is utilized in the operation of Flyback converter aswellas 31 level multi-level inverter. By using applications of renewable energy, this paper suggests a 31-level multilevel inverter, which generates waveforms with the staircase's many output levels and smaller THD level. The DC voltage obtained is converted to AC and fed into the propulsion load. The simulation is executed with the aid of MATLAB software and the RES fed to 31-level inverter for the drive application is analyzed.
