提出了一种新型霍尔推力器脉冲同步驱动系统。通过施加频率接近放电振荡频率的脉动驱动电压，可以实现霍尔推力器的稳定和同步操作。还提出了一种脉冲升压斩波器电路，该电路适合用作脉冲同步驱动器，并且作为霍尔推进器的驱动电路具有许多吸引人的功能。此外，它表明，推力性能提高约30%，在200 W的输入功率通过使用驱动电路。脉冲同步驱动是一种新型的霍尔推力器驱动方式，有望成为大功率霍尔推力器的关键技术。
A new pulse-synchronous driver system is proposed for Hall thrusters. By applying a pulsating 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 is a new driving method optimized for thruster operation, and it is expected to become an essential technology for high-power Hall thrusters.
