摘要
电推进电源(Power Processing Unit,PPU)是电推进系统的核心单机,其体积、重量及关键技术难度往往超过推力器本身。屏栅电源及阳极电源这类大功率高压电源是电推进电源系统的核心部件。针对多模式切换电推进系统的需求,提出了一种适用于宽输入电压范围屏栅电源的两级式功率拓扑架构,前级为两相交错并联Boost拓扑以实现宽范围调压,后级为工作于最优频率点的不控谐振拓扑以实现高变比隔离升压。研究该功率拓扑架构的控制方式及磁性器件的设计原则并最终给出了相应的实验结果。
Power Processing Unit(PPU)is the central part of the xenon ion electric propulsion system,and its size,weight,and key technical difficulties usually exceed the thruster itself.The high-power and high-output-voltage power supplies,such as beam supply and anode supply,are the main parts of the electric propulsion power system.In this paper,a two power stage beam supply topology is proposed to meet the requirement of multi-mode electric propulsion system.The front stage is an interleaved boost converter,which is adopted to adjust the total output voltage.The second stage is based on a full-bridge resonant converter able to provide very high output voltage,which operates the fixed optimum switching frequency.The power converter control strategy and design principles of magnetic components are studied and finally the corresponding experimental results are given to validate feasibility of the proposed converter in this paper.
