Comparative Analysis of Design of Electric Vehicle Battery Charger Using Quasi-Z-Source Converter and Luo Converter

Abstract

The development in DC/DC converters is required today because it is widely utilized in power generation using wind and solar.Hence, this work proposes two different topologies namely, a DC/DC Quasi Z Source Converter (QZSC) and positive LUO converter for solar power generated in the DC micro grid. A PV is connected as an input to converter. However, due to the varying nature of the PV, the output of the system oscillates. Hence, to maintain a constant output supply for load, PI controller is implemented.  Thus the behavior of the proposed convertersis analyzed using MATLAB simulation. From the analysis, it is demonstrated that among these two proposed converter, Luo converter exhibits high voltage gain and efficiency than QZSC.
