A secondary power supply design suitable for GSAR system

With the rapid development of space science and technology, SAR has been more and more widely used. The array secondary power supply installed on the surface of the SAR antenna is an important part of the SAR system. In this paper, a secondary power supply is designed for the G-SAR system. It converts power supplies to multiple circuits at different voltage levels. At the same time, the output voltage of the secondary power supply part has a controllable function to meet the requirements of the power-off sequence of the relevant independent equipment. To achieve the G-SAR system power distribution target.
