SINGLE-DC-SOURCE QUASI-Z-SOURCE CASCADED MULTILEVEL INVERTER WITH ACTIVE POWER SHARING

This paper proposes a novel cascaded multilevel topology, named Single-dc-Source quasi-Z Source Cascade Multilevel Inverter. inverter has the ability to provide independent regulation of dc bus voltage each H-bridge, ensuring real power balancing and true symmetric waveforms. In addition, Inverter allows operating with single low PV array. provides detailed analysis operation design methodology for hardware, as well modeling controller design. Simulation results are provided verify proposed system control strategy.
