BIDIRECTIONAL DC TO DC CONVERTER FOR ELECTRIC VEHICLE

Abstract

As the demand for electric vehicles (EVs) continues to rise, the need for efficient and versatile power electronics solutions becomes increasingly critical. This thesis explores the design, implementation, and optimization of a bidirectional DC-DC converter tailored for electric vehicles. The bidirectional converter is an integral component in EV powertrains, enabling energy transfer between high-voltage battery systems and auxiliary systems, such as electric drivetrains and on-board electronics. The thesis explores the theoretical modeling and simulation of the bidirectional converter, providing insights into its operational characteristics and performance metrics. The bidirectional DC-DC converter's integration into the electric vehicle architecture provides energy flow between the high-voltage battery and various subsystems. This thesis explores interconnection of EV to the grid by bidirectional DC to DC converter. A bidirectional DC to DC converter is an important component in the integration of energy storage systems with the electrical grid. It allows bidirectional power flow in the circuit, enabling not only the charging of batteries from the grid but also the supply of stored energy back to the grid when needed. This technology is essential for applications such as electric vehicles (EVs), where it can facilitate vehicle-to-grid (V2G) services. The converter ensures efficient power conversion and helps maintain the balance of power within the microgrid by regulating the internal DC bus voltage.
