Abstract

The invention discloses an integrated power system for a nano satellite. The system comprises a solar battery array, a storage battery group and a power controller. The solar battery array is used for converting solar energy into electrical energy to charge the storage battery group or output electricity for loads; the storage battery group is connected with the solar battery array in parallel, and used for storing the electrical energy converted by the solar battery array or outputting electrical energy to supply power for the loads; the power controller is used for regulating and stabilizing the current or voltage transmission among the solar battery array, the storage battery group and the loads; and the storage battery array is directly connected with the power controller by an electrical connector. The integrated power system for the nano satellite has the characteristics of using fewer cables, and being small in volume, high in integration level and excellent in reliability.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to an integrated power supply system for micro-nano satellites. Background technique [0002] The power system is an important subsystem of the satellite, which is used to supply power to other subsystems and payloads of the entire satellite. The power system mainly includes the power controller and battery pack inside the star, the solar array outside the star, and the cables connecting each unit. The weight of the power system generally accounts for about 30% of the entire satellite. In order to meet the design requirements of small size and light weight for micro-nano satellites, reducing the size and mass of the power system is the key to realizing the satellite miniaturization design. [0003] At present, the power controller and battery pack of satellites are independently designed, packaged, and connected by cables. The system is large in size and heavy in weight, which cannot ...
