摘要
为快速有效地发现导引头二次电源系统设计中存在的问题,在Saber仿真软件平台下对其进行仿真分析。提出了参量化建模与Mast语言相结合的方法,建立了功能齐全、特征参数符合规范的DC/DC变换器模型;运用宏建模的方法,根据元器件的功能要求、原理图,分别建立了霍尔电流传感器、电源滤波器模型,并对上述的元器件模型及构建的整个二次电源系统进行了仿真实验。仿真结果证明了所建模型均满足系统的功能要求且具有较高的精度,同时由于在DC/DC变换器建模中考虑到了纹波特性,使其可以作为传导电磁干扰模型,用以对导引头电源线传导发射CE102项目进行仿真,为系统的效能评估、电磁干扰抑制提供有益的参考。
To find the problems in the secondary power supply system design quickly and effectively, simulations are carried out under the Saber simulation software platform. The DC/DC converter model with complete performance and characteristic parameters conforming to specifications is established by combining parametric modeling with Mast language. By using the method of macro modeling, the hall current sensor and power supply filter model are established respectively based on the function, schematic diagram of the components. Also the simulation of the component model and the whole secondary power supply system are carried out. The simulation results show that the proposed model satisfies the functional requirements of the system and has high accuracy. At the same time, due to the ripple characteristics in the DC/DC converter modeling, it can be used as a conducted interference model to simulate the power bus conducted emission CE102 project, which provides a useful reference for system performance evaluation and electromagnetic interference suppression.
