Abstract

The invention discloses an on-rocket energy efficient topology system based on wireless power supply, and belongs to the rocket power supply and distribution technical field. The system adopts a composite bus full-adjustment technology, is suitable for a power supply system having higher requirement for bus voltage stability, has the advantages of not being influenced by the voltage change of a storage battery and being stable in power supply outlet voltage and good in load stability, is particularly suitable for a centralized power supply system, can achieve the autonomous charging and discharging management of the on-rocket power supply, and intensively reflects the design thought of a smart rocket in combination with a wireless energy transmission ground power supply interface.

Description

technical field [0001] The invention relates to an energy-efficient topological system on an arrow based on wireless power supply, that is, an energy-efficient topological system on an arrow based on wireless power supply, and belongs to the technical field of rocket power supply and distribution. Background technique [0002] The power supply of traditional launch vehicles is mostly distributed power supply, mainly using multiple batteries to provide primary DC power for various system instruments and equipment of the launch vehicle, including rocket control, utilization, safety, and telemetry fault detection systems to provide power. Rocket batteries are mainly zinc-silver batteries. Although this solution is conducive to fault isolation and troubleshooting, it has the advantages of high reliability and mature technology, but it also has the disadvantage that the ground test cannot use batteries for a long time, resulting in incomplete coverage of power supply tests, too m...
