The Quasi-Z-source converter (QZSC) is the favorite dc-dc converter that can be applied to applications like EV battery charging, microgrid, distributed generator, etc. QZSC is the modified version of the Z-source converter (ZSC) which has the additional qualities of uninterrupted input current and a broad range of input voltage over ZSC. In this article, QZSC is especially developed for the dc-dc like vehicle-to-vehicle (V2V) battery charging application. Due to the availability of shoot-through conditions, QZSC overcomes the burden of the additional dc-dc booster, unlike a two-stage converter. This additional benefit of the shoot-through condition makes QZSC more worthy than a conventional converter. The elaborated design analysis of the QZSC is presented in this article which found reduced voltage stress across one of the capacitors, unlike the traditionalistic impedance source converter. The hardware prototype of QZSC is developed and experimental results are obtained. The experimental results are verified by using simulation and theoretical results.Experimental results suggest that the QZSC converter concept could be most suitable for the V2V battery charging applications. Simulation results are obtained for QZSC by using a matrix laboratory.
