摘要
针对航天器用DC-DC模块电源电磁兼容设计中的发射干扰(RE102和CE102),探寻其产生发射干扰的根源,并分析了DC-DC模块电源输入输出端EMI的产生原因,阐述了工程中常用的抑制EMI的方法:滤波器设计法、印制板EMC设计法。对干扰测试结果超标的DC-DC模块电源采取相应的抑制措施后,测试结果有了显著的改善。
In this paper, the author introduce the EMI （ RE 102 and CE 102） of the spacecraft DC-DC module supply, introduced the converters produce the source of the EMI and analyzed the EMI of DC-DC converters input and output, also expatiated the engineering design method of the restraint of EMI： Filter design method, PCB EMC design method, Finally, test the result had obviously of improvement when the DC-DC converters that not pass to the EMI testing adopt to design the method of EMC,
