Abstract: A coil structure for near-field wireless power transfer, integrating the traditional inductor and external capacitor structure into one single coil and forming a series resonance. The series resonance is achieved by a terminal connection and layering method. The electric field is canceled via a distributed turn-to-turn interleaving structure. With the integrated capacitor, the costs and space of a resonant capacitor can be saved. With the canceled electric field, the interference with neighboring components, such as touch-screen, can be reduced. Other benefits can include low-profile and fabrication convenience based on RGB technology. This coil can be useful for both consumer electronics and electric vehicle wireless charging.
