The system meets the testing requirement of satellite power supply controllers of different models, and comprehensive testing can be performed on the satellite power supply controller on the ground.

Description

technical field [0001] The invention relates to an automatic performance test system for a satellite power controller, which is used for realizing comprehensive and fast testing of the function and performance of the satellite power controller on the ground, and belongs to the technical field of satellite power control and management. Background technique [0002] The spacecraft power system is an independent subsystem of the spacecraft, responsible for all the energy supply of the spacecraft during use, and is the core component of the spacecraft. The power controller (PCU) is equivalent to the brain of the entire power subsystem, coordinating the work of the entire power subsystem so that the entire power subsystem works in a state that meets the requirements of other subsystems. The performance of the PCU will directly affect the quality of the entire spacecraft power system. [0003] At present, the performance evaluation methods and methods of satellite power supply in...
