Abstract
A time average peak value of low frequency magnetic noise or low frequency conductive noise generated from a power supply device which drives a Hall thruster is suppressed without mass of a satellite significantly increased. A pulse width control circuit () of a Hall thruster power supply device () outputs a spread signal () obtained by performing spread spectrum on a pulse signal based on a control signal (). A voltage output circuit () outputs output voltage () to a Hall thruster () in accordance with the spread signal () output by the pulse width control circuit ().
