Problems solved by technology

[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.

Abstract

The present invention provides a high-power SAR satellite power supply equalization system. A power router is used to construct the paths between distributed power sources. The flow of energy is formed between the distributed power sources; it can be seen that the present invention realizes the energy balance of multiple distributed power sources on the system level through the power router, maximizes the energy storage utilization rate of SAR satellites, and guarantees the energy storage efficiency of SAR satellites. Normal operation is of great significance; in addition, the invention also uses an isolation converter to realize the isolation of the unregulated bus and the fully regulated bus, which reduces the interference coupling between the buses and improves the stability of the system operation.
