Stability Analysis and Research of SAR Satellite Power Supply System
Journal of Electrical Engineering & Technology(2024)
Abstract
The modeling analysis on the secondary load power supply and pulse load of the synthetic aperture radar (SAR) has been conducted in this paper. To satisfy the requirements of the SAR satellite power system featured with the large load platform power ratio, large capacitive pulse work, and relatively high stability of the bus bar. Meanwhile, the experiment on features of impedance had been carried out on the secondary power supply system for the satellite power system. Viewing the features of the SAR power supply system, a method has been put forward to enhance the stability of the work system. And the related work has been conducted the related stability work concerning various load modes. The experimental results are consistent with the analysis, showing that the power supply system is stable, which satisfies the need for SAR satellite payload.
