Abstract

The invention provides magnetic coupling resonance wireless power transmitting equipment and a magnetic coupling resonance wireless power transmitting method. The equipment comprises an LC resonance network with a transmitting coil, a power supply and a self-resonance control circuit, wherein the power supply is connected with the LC resonance network at a transmitting end, and charges the LC resonance network at the transmitting end; the self-resonance control circuit monitors the charging process; after the charging is finished, the self-resonance control circuit controls to cut off the power of the power supply; the LC resonance network performs self-resonance oscillating at a natural frequency and transmits the energy out in the form of an electromagnetic wave through a resonance coil in the LC resonance network at the transmitting end; when the self-resonance control circuit detects that the energy of the LC resonance network at the transmitting end is lower than a preset threshold value during a self-resonance oscillating process, the self-resonance control circuit closes the power supply; the power supply starts to charge the LC resonance network at the transmitting end. Through the equipment and the method, self-resonance intermittent wireless power transmitting can be realized without the help of external excitation.

Description

technical field [0001] The invention relates to wireless power transmission technology, in particular to a magnetic coupling resonant wireless power transmission device and method. Background technique [0002] While China is vigorously developing smart grid technology, the equipment installed on the transmission tower has no working power. The traditional method is to use a combination of solar panels and batteries to provide equipment working power. This power supply method has high maintenance costs in the later period. The high-voltage transmission line induction power acquisition technology is equipotential power acquisition, which can provide working power for equipment working on the line. However, the equipment working on the tower still has no working power supply. If the electric energy is transmitted to the tower by the wire, it is equivalent to short-circuiting the high potential and the ground potential of the transmission line, which cannot be implemented.
