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

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.
