Carrier rocket ground high-power wireless power supply system based on electromagnetic resonance

Abstract

The invention discloses a carrier rocket ground high-power wireless power supply system based on electromagnetic resonance, which comprises a ground power supply converter, a transmitting coil, a receiving coil and an energy receiving processor. The ground power supply converter and the transmitting coil are respectively placed on a ground transmitting platform or an oscillating bar; the receivingcoil and the energy receiving processor are arranged on the rocket; the ground power supply converter converts alternating current into high-frequency alternating current and inputs the high-frequency alternating current into the transmitting coil, the receiving coil converts coupled magnetic field energy into high-frequency alternating current and inputs the high-frequency alternating current into the energy receiving processor, and the energy receiving processor processes the high-frequency alternating current and then outputs power supply voltage meeting rocket load power supply requirements. Non-contact and separation-free power supply of the carrier rocket in the ground test and launch process is achieved, existing unplugging and unplugging technologies can be replaced, automatic butt joint of rocket power supply is achieved, and the defects that unplugging and unplugging cables are complex in operation, high in difficulty, large in personnel and time consumption, high in degreeof dependence on auxiliary equipment and the like are overcome.

Description

technical field [0001] The invention relates to a high-power (kilowatt level) wireless power supply system for launch vehicles based on electromagnetic resonance, and belongs to the field of wireless power supply. Background technique [0002] For a long time, launch vehicles have generally used mechanical and electrical connectors such as unplugging and unplugging as important electrical interfaces for rocket-ground connection. During the launch site test and launch preparation process, according to the test and launch process, in the subsystem and general inspection test It is necessary to perform multiple unplugging and unplugging connector separation and docking operations. Due to the weight and volume of the separated electrical connectors and the attached cables, coupled with the operating space and position (such as tail detachment connection, detachment cable) upper swing lever), the relevant operations of unplugging and unplugging cable connectors often become diffi...
