Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the ignition of the existing hollow cathode usually consists of an ignition power supply, a heating power supply and an anode power supply. Due to the large volume of the three power supplies, the entire power supply system is overweight and the system structure is complex, thereby reducing the reliability of cathode ignition. sexual problems

Abstract

The invention discloses an integrated power supply circuit of a tethered satellite hollow cathode and a power supply method, relates to an integrated power supply circuit structure for supplying powerto the tethered satellite hollow cathode, and aims to solve the problems that the conventional ignition of the hollow cathode generally consists of an ignition power supply, a heating power supply and an anode power supply; because the three power supplies are large in size, the whole power supply system is too heavy, the system structure is complex, and the cathode ignition reliability is reduced. By externally connecting the same 42V direct-current power supply, the power supply loop of the hollow cathode is reduced from a plurality of power supplies to one power supply, so the mass and thesize of the power supply loop of the hollow cathode are greatly reduced, the complexity of the power supply loop of the hollow cathode is simplified, and the ignition reliability of the hollow cathode is improved. The power supply device is mainly used for supplying power to the hollow cathode.

Description

technical field [0001] The invention relates to an integrated power circuit structure for powering the hollow cathode of a tethered satellite. Background technique [0002] The hollow cathode is the core component of the plasma contactor. The plasma contactor is used to control the space potential of the aircraft, mainly including the hollow cathode, power supply and storage supply. Tethered satellites require a hollow cathode with a current range of 0-15A as a potential controller, while the power supply and storage and supply unit work independently. Under such background requirements, it is particularly important to develop a device that integrates the hollow cathode and power supply system. [0003] The power supply used in space electric propulsion has high requirements on power density, efficiency and dynamic response speed. The ignition of the existing hollow cathode is usually composed of ignition power supply, heating power supply and anode power supply. The mass ...
