The research presented here reports enhanced-boost quasi-Z-source inverters (qZSI) using two switching impedance networks (continuous input current configuration and discontinuous input current configuration). These suggested inverter designs, which are comparable to ZSIs in that they have very powerful boost voltage inversion at a low shoot-through duty ratio and high modulation index, produce output voltage of higher quality. These suggested inverter topologies draw continuous input current and a lower voltage across capacitors compared to ZSIs with two-switched Z-source impedance networks in order to avoid the first inrush problem. They also share common ground with the source and bridge. In addition, the input’s ripple current is essentially nonexistent. In terms of operating principles and analysis, a continuous input current configuration enhanced-boost qZSI with two switching impedance networks is presented and contrasted to ZSI, ZSI, DA/CA-qZSI, and enhanced-boost ZSIs. The theoretical analysis is validated through simulation and experiment.
