New Symmetric Enhanced-Boost Modified Z-Source Inverters with Switched Z-Impedance

In this paper, two new symmetric structures are proposed to modify existing enhanced-boost Z-source inverter (EB-ZSI) by employing the same number of components in the Z-impedance network. The Z-impedance network in the first structure is connected in parallel with H-bridge circuit to form a topolog...
