星载电子设备试验的电磁干扰三要素分析

从某星载电子设备要进行的试验着手,研究了星载电子设备电磁干扰的三要素(干扰源、耦合途径及敏感部位),对电磁兼容试验的主要内容和要求进行了简介,并详细分析了三要素与电磁兼容试验项目之间的关联性。对某星载电子设备电磁兼容设计报告的基础上提炼并总结的结论,对星载电子设备的电磁兼容设计有较高的参考价值,对其他电子设备的电磁兼容设计也有一定的参考意义。

The Three Elements of EMI Tests for a Spaceborne Electronics

Based on the Electromagnetic Compatibility （EMC） tests of a spaceborne electronic equipment, the three elements （the interference source, coupling approach and sensitive components） of Electromagnetic Interference （EMI） are analyzed firstly, then the main factors in EMC tests are discussed briefly, and the correlation between the three elements and the EMC tests is analyzed in detailed. This paper gives a conclusion based on a EMC design report on a spaceborne electronic equipment, so it is not only valuable for the design of spaceborne equipment, but also very useful for other electronic equipment design.
