超大功率电推进电源处理单元关键技术研究

Key Technology of Super Power Electric Propulsion Power Processing Unit

针对深空探测等空间任务对超大功率(10~100kW)电推进系统的需求,通过对国内外超大功率电推进技术的调研,提出了一种50kW超大功率霍尔电推进系统电源处理单元(Power processing unit,PPU)设计方案,重点对核心的阳极电源关键技术进行研究,提出了四管Buck-Boost变换器和三相LLC谐振变换器级联的设计方案。

Aiming at the requirement of super power(10~100kW)electric propulsion system for deep space exploration and other space missions,through investigation and research of super power electric propulsion technology at home and abroad,a 50kW super power electric propulsion system Power Processing Unit(PPU)design scheme is put forward,and the four tube Buck-Boost converter and three-phase LLC resonant converter topology are used to design the anode power which is the core of PPU.
