A New Non-Isolated Active Quasi Z-Source Multilevel Inverter With High Gain Boost

This paper proposes a three-level diode clamped active impedance source inverter (AIS-TLI) based on the quasi Z-source (qZSI). Apart from having minimal components and inherent benefits of qZSIs, such as single-stage buck-boost capability, shoot-through (ST) immunity, continuity input current, proposed topology has higher boost capability excellent efficiency. In addition, bridge modulation index, which improves quality output waveform necessitates less inductance. The provides common ground between terminals, effectively eliminates leakage current in PV-powered single-phase systems. describes different operating modes principle, dynamic analysis, steady-state parameter selection instructions for in-depth. Furthermore, suggested inverter’s limitations are compared to traditional (q)ZSIs some other AIS-TLIs. Finally, modeling experimental results used confirm effectiveness topology.
