Problems solved by technology

[0004] The importance of supercapacitors and batteries is different, and battery charging should be given priority (batteries supply power to the aircraft platform). However, due to the limited light period of low-orbit light, it is impossible to wait for the battery to be fully charged before charging the supercapacitor. Therefore, how to solve the problem of supercapacitor charging becomes a problem. Technical Difficulties

Abstract

The invention belongs to a charging control circuit for a supercapacitor based on a non-adjusting-busbar mode of a spacecraft. The circuit can increase the charging current for the supercapacitor with the rise of the busbar voltage; when a constant voltage point of the supercapacitor is achieved, a constant voltage control state is performed. The charging control circuit comprises a super-buck voltage-reduction power module, an electric current loop-voltage loop dual-loop control module, a charging current reference follow-up busbar voltage control module, and a supercapacitor constant-current constant-voltage control module. According to the charging control circuit, the supercapacitor, serving as a backup power, satisfies the power requirement of the busbar preferably; with the increase of excessive energy, the busbar voltage rises gradually, and the charging current is increased gradually; and the charging control circuit is simple in control structure, less in required devices and simple in interface.

Description

technical field [0001] The invention belongs to the technical field of space power supplies, and in particular relates to a control circuit for a voltage-controlled current-limiting charging circuit of a supercapacitor bank. Background technique [0002] Not adjusting the busbar is an important energy control mode for space vehicles. Its characteristic is that the output current of the solar cell array is directly charged to the battery, and the battery voltage is the busbar voltage. Always changing. [0003] As an auxiliary energy source, a supercapacitor is generally connected in parallel with the battery. The supercapacitor has the ability to output high power instantaneously. Therefore, when there is a large pulse load demand, the supercapacitor will provide most of the energy for the large pulse load. [0004] The importance of supercapacitors is different from that of batteries, and priority should be given to battery charging (battery supplies power to the aircraft p...
