“…Then, the generated DC signal is the input of a DC/AC converter. This converter is usually performed using a full-bridge inverter [42][43][44][45], but there are some other topologies, such as single-ended converters [46] or multi-phase systems [47,48]. Some authors choose to include a DC/DC converter between the grid rectifier and the primary inverter.…”

Due to their flexibility, Electric Vehicles (EVs) constitute an important asset for the integration of renewable energy sources in the Smart Grid. In particular, they should have a dual role: as a controllable load and as a mobile generator with a low inertia. To perform these tasks, chargers must provide the electronics with a power flow from the grid to the vehicle and vice versa. This bidirectionality can also be implemented in wireless chargers. The power converters, the compensation networks and the coil misalignment must be considered when designing the control of these systems. This paper presents a review about the proposed algorithms to control the active and the reactive power flow in a bidirectional wireless charger.

The increasing Electric Vehicle (EV) market is driven by the desire for more efficient and reliable approaches to recharge EV batteries. Among various charging methodologies for EVs, Wireless Power Transfer (WPT) has gained more attention from EV users due to its features such as safety, low maintenance, comfort, automated operation, and reliability. The innovative WPT method replaces the conductive charging system while maintaining a similar power rating and efficiency. Numerous strategies have been devised to enhance the efficiency and reliability of the WPT model. The primary challenge in WPT is reduction in power transfer efficiency (PTE) as the gap between the coils is increased. Also, the improvement in the PTE depends on various design parameters of the WPT circuit. Therefore, this review article thoroughly investigates recent significant research literatures that explains WPT technology and tailored towards enhancement of PTE. The investigation is carried on various coil configurations, converter topologies and different critical factors to improve PTE such as impedance matching, compensation techniques. Moreover, the research gaps in WPT technology and future scope suitable for static, quasidynamic, and dynamic charging methods are presented. This research can play a crucial role in assisting developers in selecting an optimal design to enhance the WPT system.

“…However, the limitations of the charging time of the battery [2] and the autonomy are a hindrance to the use of the technology [3]. The direct consequence is the intrusion of chargers and power cables into our daily lives, which increasingly tends to limit the mobility offered by vehicles [4]- [6]. Much research effort has gone into solving these problems, and wireless power transfer (WPT) to EVs has become evident and feasible to solve this problem [7]- [9].…”
