Abstract

The invention relates to a topology circuit for power regulation of a satellite power supply system. The topology circuit comprises a 'T'-shaped integrated main circuit topology and a logic control circuit topology. The main circuit topology comprises three power MOS tubes, three separate diodes, a power diode and an energy storage inductor. The output of a solar cell array is connected with a load through the power diode to carry out power supply. The three power MOS tubes and the three separate diodes are arranged in the structure of a 'T'-shaped topology, are respectively connected with a solar array, a storage battery and a ground line, and complete the three functions of solar array shunting, storage battery charging and discharging according to logic control. The energy storage inductor is directly connected with the storage battery. The problem that the mass power of the satellite power supply system cannot meet the load capacity can be effectively solved, a technical basis is provided for the realization of a light and integrated satellite power supply system, and the topology circuit has wide application prospects in the field of satellite power supply systems.

Description

technical field [0001] The invention belongs to the technical field of power regulation topology of a satellite power supply system, and in particular relates to a topology circuit used for power regulation of a satellite power supply system. Background technique [0002] The power regulation module of the satellite power supply system converts the power emitted by the solar cell array according to certain technical requirements, adjusts it to the voltage required by the busbar, directly supplies power to the load, and controls the charging and discharging of the battery to maintain the stability of the busbar voltage of the power supply system . [0003] Compared to the existing S 3 R, hybrid and S 4 R power regulation topology technology, "T" type integrated power regulation topology technology has the advantages of fewer components used, high integration, small volume and weight, and large mass-to-power ratio. In addition, it has the advantages of control strategy diffi...
