Description

technical field [0001] The invention relates to the technical field of Hall effect thrusters. Background technique [0002] The plasma Hall effect thruster is a functional conversion device that converts electrical energy into kinetic energy of the working medium by using the joint action of electric field and magnetic field. It is one of the most widely used electric thrusters in space propulsion. Although the operating power supply of the Hall thruster is a DC discharge, the oscillation of the discharge current with a frequency range of about 1 to 100kHz has been observed in the experiment, which is called low-frequency oscillation relative to the plasma oscillation. The peak-to-peak value of the low-frequency oscillation can often reach 100% of the average value of the discharge current. Large-scale low-frequency oscillations will impact the power supply system of the Hall thruster, and may also be connected to other equipment on the satellite, affecting their normal ope...
