“…It is clear from the comparison that the proposed topology is more feasible for the practical applications as compared to the previous topologies, especially when more voltage gain and boosting ability are required and when cost, size, and lower rating of components are the main concerns. Since the proposed topology belongs to the ZSI family, it finds its applications where all other ZSI are applicable, such as in variable speed drive systems, grid-connected photovoltaic systems, distributed generation systems, hybrid electric vehicles, laminators, conveyor belts, and so on [35][36][37].

Due to the impediments of voltage source inverter and current source inverter, Z-Source Inverter (ZSI) has become notorious for better power quality in low and medium power applications. Several modifications are proposed for impedance source in the form of Quasi Z-Source Inverter (QZSI) and Neutral Point Clamped Z-Source Inverter (NPCZSI). However, due to the discontinuity of the source current, NPCZSI is not suitable for some applications, i.e., fuel cell, UPS, and hybrid electric vehicles. Although in later advancements, source current becomes continuous in multilevel QZSI, low voltage gain, higher shoot-through duty ratio, lesser availability of modulation index, and higher voltage stress across switches are still an obstacle in NPCZSI. In this research work, a three-level high voltage gain Neutral Point Clamped Inverter (NPCI) that gives three-level AC output in a single stage, is proposed to boost up the DC voltage at the desired level. At the same time, it detains all the merits of previous topologies of three-level NPCZSI/QZSI. Simulations have been done in the MATLAB/Simulink environment to show the effectiveness of the proposed inverter topology.

“…Recent solutions based on the impedance-source (IS) networks have been extended to various application areas. Z-Source inverters (ZSIs) and their derivations were proposed as promising solutions for single stage dc-ac applications [4][5][6][7][8][9]. Since then, many topological derivations have been proposed and recently a number of review papers have been published [10][11][12].…”

Solutions for a family of the novel three-level neutral-point-clamped (NPC) inductor-capacitor-capacitor-transformer (LCCT)-derived three-phase inverters are described and compared. Component design guidelines and steady state analysis, current and voltage waveforms are given. The authors' simulation results confirm the theoretical predictions. It was found that an asymmetrical three-level NPC LCCT-derived inverter with a single diode in the impedance source network is the most promising solution. Experimental results for an asymmetrical three-level NPC LCCT-derived inverter with a single input voltage source and continuous input current are presented. The main advantages and design requirements are discussed.

“…One of the characteristics of the buck inverter is that the instantaneous average output voltage is always lower than the input dc voltage [11][12][13][14][15][16][17]. Buck inverter is a dc-ac converter which can not produce an output voltage greater than the input voltage, but it is easy to be controled .This converter performs in a simplified way, turning on and off the switches to produce a bipolar square output voltage.…”

This paper introduces a new transformer less dc-ac converter with the feature that it produces an instantaneous output voltage higher or lower than the input dc voltage. The topology consists of two switching cells, well known dynamic response, does not have transformer or power conversion stage that saves us mass, losses, and volume of a transformer. The merits of step up/step down dc-ac converter includes operational reliability, reduced size of components and there by acquiring less mass for the whole converter. The advantages of buck-boost dc-ac converter when switching cells are used instead of a transformer, is also introduced. Current control takes the advantage of circuit protection from disturbance (fault). This technique can provide fast dynamic response, robust Performance. The current control of step up/step down dc-ac converter is easy to implement and provides high accuracy. The validity and performance of the discussed topology are verified by simulation using Matlab/simulink software.
