Dual-input dual-output z-source inverter

Space-Vector-Modulated Three-Level Inverters With a Single Z-Source Network

“…The Z-source concept can be applied to all dc-to-ac [26], ac-to-dc [27], ac-to-ac [28], [29], [30], [31] and dc-to-dc [32], [33] power conversion whether two-level or multilevel. The Z-source concept was extended to the NPC inverter in [34], where two additional Z-source networks were connected between two isolated dc sources and a traditional NPC inverter.…”

A Review on Industrial Applications of Z-Source Inverter

“…This inverter can control frequency, amplitude, current of dc input and phase of ac output. Moreover, the utmost point of preference of this inverter is that its outputs remain operating regardless of the possibility that one of the inputs is not available [6]. A. Pattanaphol et al [7] used Z-source inverter to figure out the shading issue of photovoltaic cell.…”

ESL-𝚪-Z- Source Inverter

“…In recent years, various Z-source inverter (ZSI) topologies have been presented in numerous diversified studies [1][2][3][4]. Some of the studies are focused on modeling and control [5][6][7][8], modulation strategy [9][10][11][12], applications [13][14][15][16], and the development of new topologies [17][18][19][20][21][22][23][24].…”

“…In [22], Trans-ZSI can obtain high boost factor, when the turns ratio of the transformer windings is over 1. In [23], Γ-ZSI can obtain high boost factor by varying the turns ratio of the transformer within the narrow range, (1,2]. In [24], it proposed an improved Z-source inverter, which can reduce the capacitor voltage stress and suppress the inrush Despite the aforementioned merits, the aforementioned Z-source inverter topologies also show the following drawbacks: 1) capacitor voltage stress is increased with the increase of shoot-through duty ratio, thus high-voltage or large capacity capacitors should be used, which may result in large volume, high cost, and reducing the life span of system; 2) inductor current stress is large, and this characteristic may also lead to large volume and high cost; 3) it regulates boost factor only by adjusting the shootthrough duty ratio, and boost factor is very small with short shoot-through zero state.…”
