| Abstract: | The discharge plasma physics characteristic and power unit output characteristic on arcjet thruster were analyzed. The positive slope control of output characteristic was achieved by means of the design of constant-current control and superposition positive feedback voltage. The arc operating was in the hlgh-voltage mode state and the thruster worked steadily. The effects of electric parameters on working performances is obtained by experiment test. |
