Problems solved by technology

[0004] The present invention provides a wireless power distribution system between spacecraft for the problem that the existing wireless charging technology cannot take into account the transmission distance and the energy transmission efficiency. The capacitor successfully combines the LCC compensation structure and the SS compensation structure, and the switching of the two compensation forms can be realized only through the control of the switch combination, thus taking into account the transmission distance and energy transmission efficiency, the structure is simple and reliable, and the operation is convenient. It can also be applied to the wireless power distribution process between spacecraft with dynamically changing spacing, and has strong practicability
