Abstract

The invention provides a satellite power supply system. The satellite power supply system comprises a satellite power supply module, a satellite load, a first travel switch and a power supply controlcircuit; and the power output end of the satellite power supply module is connected with the first end of the power supply control circuit, the second end of the power supply control circuit is connected with the power input end of the satellite load, and the third end of the power supply control circuit is grounded. The first travel switch is arranged between the first end and the third end of the power supply control circuit, and the first travel switch is switched on before the satellite and the rocket are separated, so that the first end and the second end of the power supply control circuit are switched off, and the first end and the second end of the power supply control circuit are switched on after the satellite and the rocket are separated. Therefore, the satellite is automatically powered up after the satellite and the rocket are separated, and the problem that the satellite and the rocket cannot work normally after being separated due to long-term power supply before the satellite and the rocket are separated is solved.

Description

technical field

[0001] The present application relates to the field of aerospace satellites, in particular to a satellite power supply system. Background technique

[0002] Satellites are brought from the ground to predetermined orbits by launch vehicles. When the satellite is in orbit, it converts solar energy into electrical energy and stores it in the battery to realize the autonomous power supply of the satellite.

[0003] But satellites are typically stored in launch vehicles for several days before reaching orbit. During this period, if the satellite is always powered by the battery, the power of the battery will continue to decrease, and after the satellite is separated from the rocket, the satellite may not work properly due to the low power of the battery. Contents of the invention

[0004] The purpose of the embodiment of the present application is to provide a satellite power supply system, which is used to not supply power to the satellite before the separati...
