Abstract

The invention provides a solar cell array soft start control system which comprises a bus voltage sampling circuit connected to the positive and negative poles of a power supply control unit primary bus, an overvoltage protection comparison circuit connected to a bus voltage sampling circuit, an undervoltage protection circuit which collects bus voltage to be an undervoltage protection signal, a driving execution circuit which is connected to the undervoltage protection circuit, a shunt control circuit, a first diode whose input end is connected to the overvoltage protection comparison circuitand whose output end is connected to driving execution circuit, a second diode whose input end is connected to the shunt control circuit and whose output end is connected to driving execution circuit, a primary bus undervoltage protection switch and a solar battery array shunt control switch. The invention also provides a control method of the solar cell array soft start control system, stable and reliable power supply can be provided for the operation of other subsystems of a satellite, and the failure of a whole satellite caused by the failure of a satellite power supply is prevented.

Description

technical field [0001] The invention relates to the technical field of aerospace power supply control, in particular to a solar battery array soft-start control system and a control method thereof. Background technique [0002] Power Subsystem The solar array is the main power source of the satellite. When the satellite is in the light period, the solar cell array uses the photovoltaic effect of the solar cell to convert solar energy into electrical energy with the highest possible efficiency to supply power for the entire star load. In addition, while meeting the load demand during the full-sunlight period, the solar cell array charges the whole-stellar battery with the abundant electric energy during the full-sunlight period, and the battery provides the electricity demand for the whole-sunshade period after charging. When the short-term power consumption of the satellite in the illuminated area exceeds the power supply capacity of the solar cell array, the satellite is p...
