High-power SAR satellite power supply equalization system

Abstract

The invention provides a high-power SAR satellite power supply equalization system which employs a power router to construct a path between distributed power supplies, selects two distributed power supplies which need to transmit energy according to the actual demands, and enables the corresponding path to be connected, thereby enabling the energy flow to be formed between the two distributed power supplies. Therefore, the energy balance of a plurality of distributed power supplies is realized on the system level through the power router, the energy storage utilization rate of the SAR satellite is improved to the maximum extent, and the system has important significance for guaranteeing the normal operation of the SAR satellite; besides, in the system, the isolation converter is adopted torealize isolation of the non-adjusting bus and the full-adjusting bus, interference coupling between the buses is reduced, and the working stability of the system is improved.

technical field [0001] The invention belongs to the technical field of satellite power supply systems, in particular to a high-power SAR satellite power supply equalization system. Background technique [0002] The Synthetic Aperture Radar (SAR) satellite system has a high-power pulse load. When the pulse load is working, a large current step will be generated, which will cause serious electromagnetic interference to other electrical equipment on the platform and affect the normal operation of the entire satellite. The traditional power supply system using a single bus cannot meet the requirements of interference isolation. It is necessary to use a multi-bus structure with isolation function to block the interference path and ensure the operation of equipment. As the power of SAR satellites continues to increase, the traditional centralized power supply architecture cannot meet the needs of power expansion, and a distributed system architecture is required to meet high-power...

[0002] The Synthetic Aperture Radar (SAR) satellite system has a high-power pulse load. When the pulse load is working, a large current step will be generated, which will cause serious electromagnetic interference to other electrical equipment on the platform and affect the normal operation of the entire satellite.

The traditional power supply system using a single bus cannot meet the requirements of interference isolation. It is necessary to use a multi-bus structure with isolation function to block the interference path and ensure the operation of equipment

As the power of SAR satellites continues to increase, the traditional centralized power supply architecture cannot meet the needs of power expansion, and a distributed system architecture is required to meet high-power application scenarios

For the distributed system architecture, how to realize the optimal management and scheduling of system energy, improve energy utilization, and ensure the reliability and safety of system work is a huge challenge.
