Extended Quasi-Z-Source DC-DC Converter with an Active Switched-Z-Network

On the foundation of the standard quasi-Z-source inverter, this document proposes a neoteric Z-source DC-DC converter formation for high heightens applications. Compare to enhanced-boost quasi Z-source inverter (EB-qZSI), this topology provides a smaller amount stress athwart capacitors and into the bargain, current stress across switches is impaired by half, which leads to momentous decline in conveyance losses of switches. This anticipated topology provides slightly less boost factor at low duty ratio and high modulation index at the same time as using only two L-C pairs, five diodes, one switching device and thereby plummeting the losses allied with submissive components. likewise, the proposed topology enhancements the overall efficiency of the inverter, reduces the starting inrush current problem and shares common ground between the inverter bridge and the source. The operating principle, Z-network parameters design and co-related with other impedance networks are accomplished. Finally, the simulation results for the proposed system are compared with the theoretical analysis and validated.
