Dynamic wireless power transfer (DWPT) systems are developed to address the range limitations and battery size requirements of electric vehicles (EVs). These systems require careful consideration of dynamic variations in coupling for power flow control. Despite advances in couplers, compensation, and converter topologies, challenges such as stability of control systems and lack of interoperability among different configurations remain significant obstacles in the commercialization of DWPT.
Dynamic wireless power transfer (DWPT) systems are developed as a solution to electric vehicle (EV) range limitations and battery size requirements. DWPT systems require careful consideration relative to dynamic variations in coupling for power flow control. With continued advances in development of different types of couplers, compensation, and converter topologies, the stability of control systems and lack of interoperability among different configurations remain significant challenges in the path toward commercialization of DWPT. This work provides a review of the existing coupler, compensation topologies, and control schemes to determine their effectiveness in achieving the desired control objectives. In addition, it introduces practical metrics for a system designer to consider when developing the magnetics and power electronics for a DWPT system to ensure good controllability. It also shows how the delay in communication can affect the control performance and impact recommendations for high-speed vehicle charging. The comparisons are performed and through simulations for the design of a 50-kW system using different topologies. The simulation results corroborate the guidelines developed for future designs of DWPT systems.
