Modeling and Control of Bidirectional Buck-Boost Converter for Electric Vehicles Applications

Abstract

The modelling, design consideration, and control studies of the bidirectional DC/DC buck-boost converter for usage in hybrid and electric vehicles are presented in the current work. The recommended concept includes the electric motor, the vehicle's dynamics, and their controllers. This study examines the viability of grid-connected constant current EV charging utilising a DC-DC converter with fuzzy logic control (FLC). FLC does not require intricate mathematical modelling and is simple to apply. In MATLAB/Simulink, the whole model of the system under examination was built. The resulting simulation results show the suggested architecture's strength and capacity. The results collected demonstrate that the suggested technique is suitable for a range of electric vehicle-related applications.
