Problems solved by technology

[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 rate, it also leads to low output power and solar energy utilization rate of the initial solar cell array.

Abstract

The embodiment of the present application provides a satellite DET power supply system, which is used to increase the output power of the solar battery array of the initial DET power supply system of the satellite. The power system includes a solar cell array, a power control and power distribution unit, and a battery pack. The power control and power distribution unit includes a S3R shunt regulator, MEA, and a reference voltage module; the solar cell array is used to convert the obtained solar energy into electrical energy; The S3R shunt regulator is used to perform shunt shunt control according to the differential signal; the MEA is used to amplify and integrate the difference between the reference voltage and the bus voltage obtained by the control of the S3R shunt regulator to obtain a differential signal and send it to the S3R shunt controller Output; the reference voltage module is used to generate the reference voltage; the battery pack is connected to the bus for charging and discharging according to the shunt control; the reference voltage module is specifically used to generate different target reference voltages, and the S3R shunt controller is specifically used to 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...
