Abstract

The invention relates to a system based on a three-dimensional rotatable omnidirectional wireless electric energy transmission transmitter, belonging to the technical field of wireless electric energytransmission. The system includes a full-bridge inverter circuit, a three-dimensional rotatable transmitter, a receiver, a rectifier circuit, and a resonant matching circuit, and the real three-dimensional omnidirectional power transmission can be achieved by simple geometric rotation. The rotation of the emitter around an x-axis, a y-axis and a z-axis is considered, and a rotation angle corresponding to the maximum coupling of the system during three-dimensional rotation is obtained. In the case of keeping a transmission distance constant, the power of a load can be continuously adjusted bythe geometric rotation, and the maximum coupling of the system can also be obtained in a targeted manner according to the rotation angle corresponding to a derived maximum mutual inductance. Due to the effect of a DC-AC inverter, the operating frequency of the system can be continuously adjusted from 10 kHz to 400 kHz. The system can be effectively utilized in the home or office space, and the wireless electric energy transmission can be achieved for electrical equipment at any position in a three-dimensional space.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and relates to a system based on a three-dimensional rotatable omnidirectional wireless power transmission transmitter. Background technique [0002] There are three main types of wireless power transmission, electromagnetic radiation, electric field coupling and magnetic field coupling. Among them, the magnetic coupling resonant type is very suitable for charging electronic devices in home or office space due to its high efficiency and high power transmission over a long distance. At present, Wi-Fi wireless energy transfer technology, or wireless energy transfer technology with spatial freedom, is receiving more and more attention. One of the main purposes of this technology is to enable a single three-dimensional rotatable transmitter in a room to give Wireless charging of electronic devices anywhere in the room. However, the existing three-dimensional omnidirectional wire...
