摘　　要：基于通用化、系列化和模块化的研制思想,致力于研究提高航空静止变流器(ASI)的变换效率、减轻系统重量、提高可靠性和维护性等核心技术问题。从总体研制方案、核心技术和系列化基础模块3个层面出发,采用功率扩展性能好、变换效率高、可靠性高的推挽正激电路和双降压式逆变器研制了DC-DC变换模块、DC-AC变换模块等单元模块,组合成4种航空静止变流器基础模块。研制的系列化基础模块,整机变换效率均比国外同类产品提高4.5%以上,并且在体积、重量、可靠性和可维护性等方面均具有明显优势。One main trend in the development of aeronautic static inverter （ASI） is its modularization, generalization, and standardization. This article made a study on achieving higher efficiency, lighter system weight, higher reliability, and maintainability of ASI. Because of their good power expansibility and high efficiency and reliability, the push-pull forward converter and dual buck inverter are selected as the main topology to develop the DC-DC converter module and the DC-AC inverter module, and four ASI basal modules are combined by them. The four ASI modules have improved the efficiency by 4.5% as compared with similar products manufactured at home and abroad, and have obvious advantages in terms of weight, volume, reliability, and maintainability.
