Photovoltaic system-based marx multilevel converter for hybrid modulation strategy

Abstract

The multicarrier modulation strategy seems to be the most common thread for multilevel topologies. The harmonic observations for phase-shifted and phase disposition multicarrier strategy are different for cascaded and neutral-point-clamped topologies. The novel application of the photovoltaic implementation of self-boost capable of Marx multilevel inverter with an added feature of capacitor voltage balancing is proposed in this paper. The comparison of harmonic performance with fundamental and total harmonic distortion is shown to verify the claim. The analysis and implementation of the proposed hybrid carrier-based control strategy technique show superiority over harmonic performance on different techniques for the aforementioned topology. The exemplification of mathematical analysis and control modulation of Marx multilevel inverter for photovoltaic application are presented and discussed.
