Title:
POWER SUPPLY DEVICE AND ELECTRICAL PROPULSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/140667
Kind Code:
A1
Abstract:
This power supply device (100) that supplies power to a Hall thruster (40) which is an electrical propulsion device having a channel (45) that accelerates ions and generates thrust, is provided with an anode power supply (11) that generates a voltage to be applied to an anode electrode (43) provided inside the channel, and a control unit (10) that controls the anode power supply. The control unit controls the anode power supply so that the voltage to be applied to the anode electrode becomes a voltage that is obtained by superposing an alternating current voltage, at a frequency at least 10 times the discharge fluctuation of an anode current that is the current flowing through the anode electrode, on a direct current voltage.
