High gain novel two input two output buck-boost converter for electric vehicle applications

Abstract

ABSTRACT With the advancements in electric vehicles in the market, it is necessary to rephrase the converter for effective gain. The proposed Two Input – Two Output (TITO) converter accepts input from two sources: Battery and Solar PV panel included with non-isolated buck, boost, and buck-boost DC–DC converters. Also, the proposed TITO converter topology uses only three switches when compared to conventional multiport converters where the number of semiconductor switches is higher. The conventional converter has a higher number of components, whereas the proposed converter has a reduced number of conduction components as well as switching semiconductors. As a result, there is a reduction in energy lost. The proposed topology is designed and simulated in MATLAB Simulink and observed with a lower ripple voltage during buck, boost and buck-boost mode. Experimental setup results are also obtained from a prototype of the proposed converter, which confirms the theoretical considerations and effectiveness of the proposed topology.
