Abstract: In this paper, various novel pulse width modulation techniques are proposed, which can minimize the total harmonic distortion and enhances the output voltages from five level inverter to multilevel topologies. Multilevel inverters are important for power electronics applications such as flexible ac transmission systems, renewable energy sources, uninterruptible power supplies and active power filters. Three methodologies adopting the constant switching frequency, variable switching frequency multicarrier, phase shifted carrier pulse width modulation concepts are proposed in this paper. The above methodologies divided in to two techniques. The subharmonic pulse width modulation cascaded multilevel inverter strategy, minimized total harmonic distortion and switching frequency optimal pulse width modulation cascaded multilevel inverters strategy, enhances the output voltages. Field programmable gate array has been chosen to implement the pulse width modulation due it!
s fast proto typing, simple hardware and software design. Simulation and Experimental results are provided.
Keywords: Constant switching frequency, variable switching frequency, multicarrier pulse width modulation, phase shifted carrier pulse width modulation, subharmonic, switching frequency optimal, cascaded multilevel inverter
