Abstract : The rapid development of modern electric vehicles (EVs) has significantly increased the focus on energy efficiency, sustainability, and advanced power management techniques. One of the key aspects receiving considerable attention is energy recuperation, which allows vehicles to recover and reuse energy that would otherwise be lost, particularly during braking or deceleration. This concept plays a vital role in improving the overall efficiency and driving range of EVs. To effectively implement energy recuperation and enable efficient energy exchange, the use of bidirectional power converter topologies has become essential. Bidirectional converters facilitate the flow of energy in two directions, enabling both charging and discharging operations. In the context of EVs and smart grid integration, this functionality supports not only grid-to-vehicle (G2V) charging but also vehicle-to-grid (V2G) operation, where stored energy in the EV battery can be fed back into the grid when required. Such capabilities contribute to load balancing, peak shaving, and improved grid stability. Among various bidirectional converter topologies, the Dual Active Bridge (DAB) converter has emerged as a highly efficient and flexible solution. The Dual Active Bridge converter consists of two active full-bridge circuits connected through a high-frequency transformer. This configuration provides galvanic isolation, which enhances safety and reliability, especially in high-power applications such as EV charging stations. The use of high-frequency transformers also enables compact design and reduced size compared to traditional low-frequency systems. The power transfer between the two bridges is controlled by adjusting the phase shift between their switching signals, allowing precise control of energy flow. One of the major advantages of the DAB topology is its ability to operate efficiently over a wide range of power levels. It supports zero-voltage switching (ZVS), which minimizes switching losses and improves overall efficiency. Additionally, the symmetrical structure of the DAB converter makes it inherently suitable for bidirectional operation without requiring significant modifications. These features make it an ideal candidate for EV charging infrastructure, where both fast charging and energy feedback are necessary. In this research, a Dual Active Bridge converter is utilized for the construction of an advanced EV charging station capable of bidirectional energy transfer. The system is designed to not only charge electric vehicles but also store excess energy in the grid or in auxiliary energy storage elements such as batteries or supercapacitors. This flexibility enables efficient utilization of available energy resources and supports the integration of renewable energy sources like solar and wind power.
