Abstract
Electric Vehicles (EVs) are increasing in numbers at a rapid rate. In this phase change of the automobile sector for charging the electrical vehicles is one major barrier. Also, due to the limited range of single charge, range anxiety is an unresolved issue. This can be overcome by using on-road dynamic wireless charging. Also, to make the journey green, an on-board solar PV roof is considered as another charging source. To control the charging voltage for PV and dynamic charging, the buckboost converter is required as factors such as speed, ground clearance (different brands of EVs), misalignment, etc. can increase or decrease the charging voltage. Thus, this paper analysed a dual input buck-boost converter (DIBBC) and proposes charging of EV battery by solar PV and DynamicWPT. Investigation related to PV is not discussed in the paper. DIBBC small-signal model is derived and used to design a controller for three switches. Simulink model of the DIBBC is developed and the results of the simulation and performance of the DIBBC are discussed.
