Abstract:

Dynamic wireless power transfer (DWPT) for electrical vehicle (EVs) is a promising technology that can alleviate mileage anxiety and address on-board battery capacity limitations. However, there are power fluctuation and interoperability problems in DWPT systems. In order to solve these two issues, this paper proposes a decoupling self-adaptive two-pole interoperable receiver. The receiver coils are decoupled by partial overlapping. During the EV movement, the receiver coil can automatically change its polarity according to the mutual inductance variation. In this way, the secondary-side rectifier presents a series or parallel connection and produces a smooth equivalent mutual inductance fluctuation within the moving range, thus achieving a smooth output. Meanwhile, the proposed receiver can be tolerant with the unipolar and bipolar transmitter coils, capable of outputting the same power level and high transmission efficiency. The experimental results validate the effectiveness of the proposed DWPT system. IEEE
