A Compact Integrated Converter for Plug-In Electric Vehicles

Plug-in electric vehicles have gained interest in recent years, to make pollution free environment in future. A key attribute of plug-in electric vehicles is their ability to be recharged from electrical outlets. In a conventional system, onboard converters are used for charging purposes in plug in mode of operation (Static mode) has been mounted in the vehicle. However, for propulsion and regenerative braking mode of operation (Running modes), a bidirectional DC-DC converter is used, and it is integrated with the vehicle's power train components. In order to overcome the conventional methods, a compact integrated converter for plug-in electric vehicles has been proposed in this work. The compact integrated converter which operates in three modes namely plug-in charging mode, propulsion mode, regenerative braking mode, has been placed along with the power train components of the vehicle. The Proposed work focused on simulating the integrated buck-boost converter on plug-in charging mode with two-loop control strategy using MATLAB software. The battery charging of 8 kW/h using a single-phase supply on the proposed configuration was observed in the simulation.
