摘要
Abstract
In order to meet the needs of ion thruster in multi﹣operating point adj ustment in aster﹣oid exploration,the topological structure of beam supply in ion﹣thruster Power Processing Unit (PPU)is taken as the research obj ect.The article introduces the status trend and application and analyzes the characteristics of each beam supply topology.Finally,it has come up with LLC to﹣pology to meet the mission requirements.By analyzing the working characteristics of the LLC to﹣pology and meeting the wide﹣range input requirements,a simplified time﹣domain gain curve model is proposed.Combined with the current research on topology,the technical prospects of digital control mode,three level resonant converter and hybrid control are made in three aspects, which provides technical references for the development of high efficiency and light weight ion thruster PPU beam supply in the future.关键词
