HALL THRUSTER POWER SUPPLY DEVICE AND METHOD FOR CONTROLLING HALL THRUSTER POWER SUPPLY DEVICE

Title:

HALL THRUSTER POWER SUPPLY DEVICE AND METHOD FOR CONTROLLING HALL THRUSTER POWER SUPPLY DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/069994

Kind Code:

A1

Abstract:

The present invention suppresses, without greatly increasing the mass of a satellite, the time average peak value of a low-frequency magnetic noise or a low-frequency conduction noise generated from a power supply device which drives a hall thruster. A pulse width control circuit (22) of a hall thruster power supply device (10) outputs a spread signal (58) obtained by performing spread spectrum on a pulse signal on the basis of a control signal (54). A voltage output circuit (21) outputs an output voltage (52) to a hall thruster (50) in accordance with the spread signal (58) outputted by the pulse width control circuit (22).
