A single-phase Cascaded H-bridge eleven level inverter for grid-connected photovoltaic system was developed in this paper. The discrete sine area equalization pulse width modulation technique was used for modeling. The particle swarm optimization algorithm was used for eliminating the harmonic distortion.The performance of the inverter was found to be better for the discrete sine area equalization pulse width modulation technique. The harmonic spectrum and output waveforms for various load conditions were obtained for both DSAE PWM and OHSW-PWM techniques. It was also found that DSAE PWM technique can handle load variations by maintaining total harmonic distortion.
