Steady-State and State-Space Analysis of Two Switched-Impedance Network Enhanced-Boost Series-Z-source Inverter

In this broadside, steady-state as well as state-space analysis of the enhanced-boost series-Z-source inverter (EB-SZSI) is supported out. Analogous to predictable EB-(q)ZSIs, this projected inverter analysis situs keeps identical high voltage lift at low-slung duty ratio and high modulation index to afford healthier eminence output wave shape besides diminish the switch stress. Additionally, the proposed topology provides less voltage across the capacitors. Consequently, inferior grade capacitors can be hand-me-down to condense the size, cost, and weight of the system. Besides, akin to EB-qZSI, this anticipated topology is able to unravel the unruly of starting inrush current, shares common ground with source and bridge inverter. This paper presents the steady-state analysis and compares with conventional ZSI, SL-ZSI, EB-ZSI, and EB-qZSIs. Moreover, the state-space analysis of the proposed topology is also carried out. Finally, the validation of theoretical analysis of the proposed inverter topology is verified in MATLAB/Simulink with 60 V dc input voltage and 110 Vrms as output voltage.
