航空航天器配电变换器测试性设计及其仿真研究

Testability Design and Simulation Research for Distribution Converter of Aerospace Vehicle

文章首先介绍了航空航天器配电系统的组成和作用,进而指出了对配电系统进行测试性设计的实际工程意义。结合航空静止变流器为例详细论述了此类配电变换器装置的性能、组成结构和控制方法,提出了一种基于测试可控性设计以较低成本实现航空静止变流器的板级电路故障诊断方案,给出了系统故障诊断逻辑判断流程。最后搭建了航空静止变流器的仿真模型,通过详细分析变流器系统仿真结果,验证了该方案的可行性。

The structure and function of power distribution system in aerospace vehicle are pointed out in the first place.Then,the important meaning of design for testability of power distribution system is indicated.Using the aeronautical static inverter as an example,its performance,structure and control principle are presented.Then it brings forward a fault diagnosis method and logic flow of fault diagnosis based on low cost,and its operation models are designed.In the end,from the simulation results of the aerona...
