Space power supply system for last-stage rail remaining application

Abstract

The invention provides a space power supply system for last-stage rail remaining application. The system comprises a plurality of energy supply units, a plurality of storage battery charging regulators, an energy placement unit, a solar cell array, a storage battery pack and a data management computer; the storage battery charging regulators are used for obtaining a primary power supply of the power supply system and transmitting the primary power supply to the energy supply units; the energy supply units are used for obtaining a secondary power distribution power supply of the power supply system and respectively transmitting the secondary power distribution power supply to the energy placement unit and the data management computer; each energy power supply unit corresponds to one path of secondary power distribution power supply, and each path of secondary power distribution power supply is correspondingly provided with a switch; the energy placement unit is used for supplying power to each load by each path of secondary power distribution power supply through the switch corresponding to the secondary power distribution power supply; and both the solar cell array and the storage battery pack are electrically connected with the storage battery charging regulators. Compared with the prior art, the system is low in cost and small in size.

Description

technical field [0001] The invention relates to the field of space-borne integrated electronics, in particular to a space power supply system for final-stage orbital applications. Background technique [0002] In recent years, the field of aerospace technology has achieved rapid development. With the development of electronic technology, computer technology, control technology and other fields, the demand for space missions continues to increase, and it also increasingly presents the characteristics of diversity and complexity. However, due to the limitation of orbiting opportunities and carrying conditions, only a small number of new technologies have been verified in orbit. [0003] The application system of the final stage staying in orbit is an integral part of the actual orbital entry of the launch vehicle. After the rocket is launched, the final stage and its components can run in orbit for a long time, which is very suitable for space flight tests. And compared with...

Problems solved by technology

[0005] However, there are two key problems that the traditional space power system architecture has not been applied to the last-stage rail application system: one is the high price; the other is that the maximum output power of the solar panels cannot be utilized, which leads to The power system is too heavy and oversized
