一种用于航天器空心阴极电源的高功率密度、高效率及快速动态响应的新型电源耦合方法

This paper presents a coupling method of power supplies to improve power density, efficiency, and dynamic response by taking the case of heater supply, ignitor supply, and keeper supply for hollow cathode of an all electric propulsion (AEP) Hall thruster. The working principle and timing characteristic of the coupled supply, as well as the three-loop control, current sampling and chopping switch c...
