A new pulse-synchronous driver system is proposed for Hall thrusters.By applyingapulsating drive voltage with a frequency close to that of the discharge oscillation, the stable and synchronized operation of a Hall thruster can be realized. A pulsating boost chopper circuit is also proposed that is suitable for use as a pulse-synchronous drive and has many attractive features as the driver circuit for Hall thrusters. Moreover, it is demonstrated that the thrust performance is improved approximately 30% at 200 W input power by using the driver circuit. Pulse-synchronous driving isa new driving method optimized for thruster operation, and it is expected to become anessential technology for high-power Hall thrusters.
