Abstract

The embodiment of the invention provides a DET power supply system of a satellite. The DET power supply system is used for improving the output power of a solar cell array of the DET power supply system of the satellite at the initial stage. The power supply system comprises a solar cell array, a power supply control and distribution unit and a storage battery pack. The power supply control and distribution unit comprises an S3R shunt regulator, an MEA and a reference voltage module. The solar cell array is used for converting the obtained solar energy into electric energy; the S3R shunt regulator is used for carrying out shunt control according to the differential signal; the MEA is used for carrying out amplification and integration according to the difference value between the referencevoltage and the bus voltage obtained through control of the S3R shunt regulator to obtain a differential signal and outputting the differential signal to an S3R shunt controller; the reference voltage module is used for generating the reference voltage; the storage battery pack is connected with a bus and used for charging and discharging according to shunt control; the reference voltage module is specifically used for generating different target reference voltages; and the S3R shunt controller is specifically used for carrying out control according to the target differential signal control to obtain different target bus voltages.

Description

technical field [0001] This application relates to the field of satellites, in particular to a satellite DET power supply system. Background technique [0002] Small satellites usually have the characteristics of high integration, and correspondingly, in small satellites, their power systems also have the characteristics of high integration. [0003] The existing power system of small satellites can adopt the power system of Direct Energy Transfer (DET) technology, referred to as DET power system. DET power system has the characteristics of high transmission efficiency. [0004] In the existing DET power system, due to the characteristic that the power point cannot be adjusted, in order to ensure the output power of the power system at the end of the life of the small satellite, the calculated voltage of the maximum power point at the end of the solar array is usually fixed. While the battery array can output the maximum output power and the highest solar energy utilization...
