Inter-spacecraft near-field wireless energy transmission system

Abstract

The invention relates to an inter-spacecraft near-field wireless energy transmission system which comprises wireless energy signal ends arranged in various spacecrafts, wherein each wireless energy signal end has a wireless energy transmission operating state and a wireless energy reception operating state, and includes a spacecraft power controller, an inverter / rectifier circuit and an energy transmitting / receiving circuit which are in successively bidirectional connection and a voltage regulating circuit in unidirectional connection between the rectifier circuit in the inverter / rectifier circuit and the spacecraft power controller. The spacecraft power controller controls the input and output of the spacecraft energy and the handshake control of the energy transmission. The inverter / rectifier circuit inverts the DC power into high-frequency AC power or rectifies the high-frequency AC power into DC power. The energy transmitting / receiving circuit transmits an alternating electromagnetic field or receives the alternating magnetic field. The voltage regulating circuit regulates the voltage of the rectified DC power during energy reception. The system is provided with a structural body for energy transmission and reception to realize bidirectional peer-to-peer wireless energy transmission.
