摘要
简要介绍了航天控制器系统中电磁兼容的设计,并详细地介绍了1553B总线的电磁兼容的设计,对航天系统控制器的电磁环境特点进行了分析,提出了电磁兼容设计中新思路,解决了消除航天控制器系统中可能出现的各种电磁干扰和泄漏,从而使各项指标满足总体以及国军标GJB1143和GJB151A对电磁兼容性的要求。同时将问题的解决提到了设计与开发的过程,为1553B总线的硬件设计、电磁兼容、可靠性设计提供了参考。
In this paper, the electromagnetic compatibility design for controller in space system is presented. The electromag- netic compatibility design for 1553B was described in detail. Analysis is performed on the characteristics of electromagnetic environment in space system. New thought of electromagnetic compatibility design was put forward, which eliminated the electromagnetic interference and leakage and meet the demand for GJBl143 and GJB151A. Moreover, it provided the reference for hardware design, electromagnetic compatibility, and reliability design of 1553B.
