A Novel Common-Ground-Type Nine-Level Dynamic Boost Inverter

Recently, inverters with a common ac and dc ground are gaining significant interest due to their zero common-mode voltage that made them particularly attractive for the solar photovoltaic application. However, source current of existing topologies is discontinuous, gains limited. This article proposes novel common-ground-type boost inverter achieves continuous significantly enhanced dynamic gain. It consists one inductor, four capacitors, nine power MOSFETs, two diodes. Voltage boosting generation nine-level achieved concurrently within single-stage operation. The operation proposed CGT-9L-BI analyzed. Simulation experimental results presented validation.
