An invertible wireless charging system based on solar automatic tracking is designed. The sun＇s rays are tracked automatically by the system in real time to keep receiving the maximum energy. And electrical devices are charged by the energy passing through the inverter and wireless charging module. Solar high efficiency use is realized by dual-axis tracking method of the system. Wireless charging module is a new exploration for new charging methods. Experimental results show that the angle of sun rays at present can be detected accurately by a four-quadrant electro-optical detector in real time. Solar cell panel can be droved rapidly by dual-axis mechanical structure to move to the specified location. The maximum output power of the inverter is 1 000 W. And electrical de- vices with low power are charged rapidly and effectively by wireless charging module.
