“…I MPEDANCE-source networks provide an efficient means of power conversion from/to a source or load in a wide spectrum of electric power conversion (dc-dc, dc-ac, ac-dc, ac-ac) applications [2], [3]. Since the publication of the first impedancesource network called a "Z-Source Network" in 2002, many modified and new impedance-network topologies have been reported in the literature with both buck and boost capabilities, e.g., quasi-Z-source [4]- [6], Γ-Z-source [7]- [9], T-source [10], [11], Trans Z-source [12]- [14], TZ-source [15], LCCT Z-source [16], [17], TSTS Z-source [18], [19], intermediate-transformerisolated Z-source [20], distributed Z-source [21]- [23], switched inductor/capacitor [24]- [28], capacitor diode assisted [29], [30], embedded Z-source [31]- [33], semi Z-source/quasi Z-source [34], [35], enhanced/improved Z-source [36]- [39], and finally Y.
