This paper upgrades the single-excited magnetic resonant WPT system to the multi-excited magnetic resonant WPT power supply area, and proposes a winding connection principle for constructing an omnidirectional power supply area. By changing the winding connection mode of the excitation coil, the magnetic field distribution in the wireless power supply area is changed to form in the enhanced area and weakened area of the magnetic field, the power receiving terminal can improve the degree of energy coupling and power transmission efficiency by changing its degree of freedom in the area. The distribution of the magnetic field under different winding connection modes is analyzed and summarized. In the end, the experimental results of the open resonant wireless charging area platform built by the experiment are consistent with the theoretical analysis and simulation results.
