“…Three different inverters were investigated in different applications and it is shown that 'Z-source' inverter is very promising in power converter applications. Florescu and other authors in [1] have highlighted the advantages, limitations and disadvantages of Z-source converter. Peng has presented several power converter configurations [7] that overcomes the limitations and problems of traditional power source converters.…”

“…The unique feature of the Z-source converter is that unlike the traditional converters it can be open and shortcircuited which provides a mechanism for main circuit to step-up or step-down the voltage as desired [1]. Hence the output voltage can be of any value between zero and infinity i.e the obtainable range of voltage is quiet wide.…”

This paper presents a brief review of Z-source converter. This converter employs a unique impedance network to couple the converter main circuit to the power source thereby overcoming the limitations of the traditional converters and provides a novel power conversion concept. This new converter topology is examined with Unified Power Flow Controller(UPFC) and a simulation study was carried out in MATLAB-Simulink. The results of simulation indicate that Z-source converter(ZSC) can be a good alternative to Voltage Source Converters(VSC). Further investigations are being carried out to assess its suitability and its superiority for UPFC applications.

“…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.…”

“…The Z-source inverter has two capabilities such as, shoot-through duty cycle and modulation index. But the drawback of Z-source inverter is that the Z-source inverter has lower average switching device power in low boost ratio range [9][10][11][12].…”

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.
