A class of optimal multilevel inverters based on sectionalized PWM (S-PWM) modulation strategy
The paper extends previous work on a novel multilevel PWM strategy to design and implement an optimal inverter for a stand-alone PV application. This modulation strategy produces a much higher fundamental output compared to conventional SPWM without any pulse dropping. Phase-shifted carriers have been used to produce a harmonically superior SPWM signal. A higher fundamental coupled with harmonic elimination through phase shifted carriers reduces THD and improves conversion efficiency. The simulation results have been validated through an experimental prototype.
