Abstract

The invention belongs to the field of wireless power transmission and particularly relates to a primary-secondary self-coupling magnetic resonance wireless power transmission device and an operation method thereof. The primary-secondary self-coupling magnetic resonance wireless power transmission device comprises an input circuit, transmitting coil series resonance capacitors, a primary-secondary self-coupling magnetic resonance coil, receiving coil series resonance capacitors and a shaping and loading circuit. The input circuit comprises an input alternating current power supply, alternating current power supply impedance and a high-frequency high-power resonance transmission power supply. The primary-secondary self-coupling magnetic resonance coil comprises a transmitting coil, a receiving coil, a single-coil open-loop structure of a primary-secondary self-coupling coil, a single-coil closed-loop structure of the primary-secondary self-coupling coil, a multi-coil open-loop structure of the primary-secondary self-coupling coil and a multi-coil closed-loop structure of the primary-secondary self-coupling coil. By means of the primary-secondary self-coupling magnetic resonance wireless power transmission device, high power, high frequency and compact space of magnetic resonance wireless power transmission can be effectively achieved.

Description

technical field [0001] The invention belongs to the field of wireless power transmission, in particular to a master-slave self-coupling magnetic resonance wireless power transmission device and an operation method thereof. Background technique [0002] It has always been the dream of human beings to transmit electric energy wirelessly like radio waves. For more than 100 years, many scientists and engineers have been persistently carrying out this research and application. The electromagnetic resonance wireless power transmission system was first proposed by researchers at the Massachusetts Institute of Technology. Different from the electromagnetic induction transmission used by the Qi standard, the electromagnetic resonance transmission does not emit electromagnetic waves, but only forms an electromagnetic wave around it. Radiated electromagnetic wave field. The strength is similar to the strength of the earth's magnetic field, it will not have adverse effects on the human...
