Description

technical field [0001] The invention relates to a power supply scheme for the anode of a Hall electric thruster, in particular to a system and method for starting a Hall engine power supply. Background technique [0002] According to the working characteristics and power supply requirements of the anode of the Hall electric thruster, when the Hall electric thruster starts and works in a steady state, a 310V DC voltage is required to supply power to the anode of the Hall electric thruster. In a short period of time when the ignition was successful, the Hall electric thruster had a period of unstable operation, and then gradually stabilized. The duration of the unstable working state of the Hall electric thruster is related to the amplitude of the vibration and the method of power supply. [0003] The current method of supplying power to the anode of the Hall electric thruster is: when the ignition is started, add the 310V DC voltage output by the power supply to the anode of...

Problems solved by technology

[0005] 1 The success rate of ignition is not high, and the ignition is easy to turn off suddenly at the moment of ignition;

[0006] 2. The start-up oscillating current of the anode of the engine is relatively large, which affects the life of the Hall electric propulsion system;

[0007] 3 At the moment of successful ignition, the working state of the anode power supply suddenly jumps from no load to full load, which has a large impact on the anode power supply system and the power supply bus, affecting the life of the anode power supply and easily triggering the bus overcurrent protection
