This thesis is aimed to realize the four-coil spatial omnidirectional wireless power transfer combined with energy harvesting and power control. Dual source wireless charging for wireless sensor node devices in the spatial torus area. The system proposed in this thesis is a four-coil coupling structure including a feeding coil circuit, first resonant coil network, second resonant coil network and a power recieve coil circuit, in the second resonant network be a dual frequency composite resonance capable of receive dual source power energy harvesting circuit. In order to achieve omnidirectional wireless power transmission, the feeding coil circuit is composed of two mutually orthogonal diamond coils, and the current phase control is realized by FPGA to make the transmission coil current orthogonalize, so that the surrounding magnetic field vector forms a circular magnetic field trajectory. Through experimental measurement, when the transmission supplies power to the wireless sensor node device in an annular space with a distance of 30 cm, the receiving voltage on the load side is about 4.4 V, and the receiving power is 240 mW. When the second resonant network receives the second emission source, the power is stored to a 50 mF supercapacitor.
