Authors
abstract
in this paper, a new circuit is proposed for step-up z-source inverter based on qzsi (quasi-z-source inverter). the proposed topology inherits all advantages of the conventional topology. the proposed topology in comparison with conventional topology reduces the st (shoot-through) duty cycle by over 25% at the same voltage boost factor. theoretical analysis of the proposed qzsi in the st and non-st operating modes is described. then in order to show the performance of the proposed zsi, the simulation results on pscad software are used.

In this paper, a new structure of HFTI-qZS-CMI has been proposed. The proposed structure is capable of generating high-voltage for medium to high power applications. By adding a switch, a capacitor and a high-frequency transformer and also eliminating an inductor from each qZS-CMI cell, the HFTI-qZS-CMI structure will be created. Using the high-frequency transformer in the proposed structure, l...
full textTwo Inputs Five-Level Quasi-Z-Source Inverter
This paper combines quasi-Z-source into a typical five-level inverter, which includes two dc voltage sources, two quasi-Z-sources and five switching devices. In this structure, the output voltage amplitude is not limited to dc voltage source and it can be increased by quasi-Z-source. Besides, due to nature of Z-source families, this new structure is reliable and higher efficiency. Also, in this...
full textAn Energy Stored Quasi Z Source inverter for Photovoltaic Application
Abstract: The quasi-Z-source inverter (qZSI) with battery operation can balance the stochastic fluctuations of photovoltaic (PV) power injected to the grid/load. This work proposes a new topology of the energy-stored qZSI to overcome this disadvantage and delivers the continuous power to the grid/load. The operating characteristic of the proposed solution is analyzed in detail and compared to t...
