Abstract

The invention provides a magnetic-coupling resonant wireless power transmission system and method. The system comprises a transmitting device and a receiving device. The transmitting device comprises a transmitting terminal LC (inductor-capacitor) resonant network, a power supply and a self-resonant control circuit; the power supply charges the transmitting terminal LC resonant network; after the self-resonant control circuit is charged, the power supply is disconnected; the transmitting terminal LC resonant network automatically resonates and oscillates under inherent self-frequency; a resonant coil in the transmitting terminal LC resonant network transmits energy out in a form of electromagnetic wave; the receiving device comprises a receiving terminal LC resonant network and an adaptive regulating circuit; a resonant coil in the receiving terminal LC resonant network senses the electromagnetic wave and generates resonant oscillation; the adaptive regulating circuit allows the receiving terminal LC resonant network and the transmitting terminal LC resonant network to generate magnetic-coupling resonance by regulating the inherent frequency of the receiving terminal LC resonant network. The problems such that in the traditional wireless power transmission scheme, high-frequency control is difficult and adaptability is poor are solved.

Description

technical field [0001] The present invention relates to wireless power transmission technology, in particular to a magnetic coupling resonance wireless power transmission system 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 implemen...
