摘要
Misalignment tolerance ability and vertical distance adaptation are equally vital for both the power transfer and the data exchange in simultaneous wireless power and data transfer (SWPDT) systems. The coupling mechanism with the anti-series coil is explored in detail, and it is proven that not only the misalignment tolerance but also the vertical distance adaptation can be significantly improved with the well design parameter. Data is injected into the anti-series coil and extracted from the partial receiving coil. The data transfer link is analyzed, and the anti-series coil and the number of turns of the inside receiving coil are designed to stabilize the mutual inductance. Moreover, the method of distribution compensation capacitors is proposed to suppress the power interference and reduce the voltage stress of capacitors and coils. The 868-watt prototype is constructed for validation. The result shows that the load current is maintained constant well within the 100 mm misalignment distance, and DC-DC efficiency is 85.12%. Also, the transferred data is correctly recovered at the rate of 115.2 kbps in the given displacements.
