Abstract

The invention discloses a low-frequency oscillation suppression outer loop of a Hall effect thruster. The low-frequency oscillation suppression outer loop comprises a discharge power supply, a heatingpower supply, an igniter, a first inductor, a second inductor, a first capacitor and a second capacitor, the anode of the discharge power supply is connected with one end of the first inductor and one end of the second inductor. The other end of the first inductor is connected with one end of the second capacitor and the anode of the Hall thruster. The other end of the second inductor is connected with one end of the first capacitor; the cathode of the discharge power supply is connected with the cathode of the heating power supply, the other end of the first capacitor, the other end of the second capacitor, the common negative end of the Hall thruster cathode and the cathode of the igniter; the anode of the igniter is connected with the contact holding electrode of the cathode of the Hall thruster; and the anode of the heating power supply is connected with the heating end of the cathode of the Hall thruster. The low-frequency oscillation suppression outer loop of the Hall effect thruster has the advantages of being small in size, light in weight and low in direct-current power consumption.

Description

technical field [0001] The invention relates to the technical field of Hall-effect thrusters, in particular to a low-frequency oscillation suppression outer circuit of a Hall-effect thruster. 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 t...
