This paper focuses on dynamic wireless power transfer for electric vehicles and proposes a vehicle-side control method for real-time power control and efficiency maximization. The proposed control strategy and controller design are presented based on a real-time estimation of the mutual inductance between a transmitter and a receiver. Simulations and experiments demonstrate that the proposed method can achieve the maximum efficiency and the desired power simultaneously. The transmitter and the

... eceiver coils are shown in Figure 1 . They are compensated by resonance capacitors for WPT via magnetic resonance coupling [9] , which can achieve a highly efficient mid-range transmission and robustness to misalignment. In this paper, a series-series (SS) compensated circuit topology is used and its circuit diagram is shown in Figure 2 [10]. The transmitter and the receiver are characterized by the inductances L 1 , L 2 , the series-resonance capacitances C 1 , C 2 , and the internal EVS29 International Battery, Hybrid and Fuel Cell Electric Vehicle Symposium
