A family of switched-impedance network enhanced-boost quasi-Z-source inverters

This paper proposes a family of novel enhanced-boost quasi-Z-source inverters (EB-qZSIs). For the similar input voltage and shoot-through duty ratio, to that Z-source inverter/enhanced-boost qZSIs, presented topologies provide very high boost at modulation index with improved quality output waveform. Compared EB-ZSI EB-qZSIs, these less capacitors stress, which reduce volume cost system. Akin traditional impedance networks share joint ground source inverter bridge, also reduces initial inrush current. Among four types proposed configurations, type-1 discontinuous current (DIC) EB-qZSIs offers fewer stress athwart little start-up condition. Consequently, is considered illustrated for examination, simulation, hardware execution. The steady-state operation derivation factor, peak direct current-link (DC-link) capacitor voltages are derived both continuous conduction mode (CCM) modes (DCM). Z-network elements design, evaluation other Z-networks carried out. Lastly, hypothetical investigation confirmed simulation experimental tests.
