Satellite power supply subsystem with dual-guarantee power supply and distribution function

Abstract

The invention discloses a satellite power supply subsystem with a dual-guarantee power supply and distribution function, belongs to the technical field of power supply systems, and aims to solve the problem that a single-machine power supply mode of an existing satellite power supply system is single, so that a single-machine power supply circuit cannot automatically return to normal when a fault occurs. The solar cell array and the battery pack are combined, the dual-guarantee power supply and distribution function is achieved, stable operation of a satellite in various environments is ensured, the system adopts the MPPT adjusting technology, the maximum power point of the solar cell array is automatically tracked, the electric energy conversion efficiency is improved, and meanwhile the system is suitable for popularization and application. The provided battery pack can provide continuous electric energy for the satellite when illumination is insufficient, the remote control function allows ground personnel to remotely monitor and adjust system settings, the maintainability of the system is enhanced, and the system is of great significance in improving the energy utilization efficiency and stability of the satellite.
