雷达电磁环境复杂,电磁兼容性问题越来越突出。大量开关电源已在雷达系统中应用,就要求它既不产生过大的干扰,又具有一定的抗干扰能力。开关电源电磁兼容技术已越来越成为雷达电源行业研究的热点,文中分析了开关电源电磁干扰的机理,提出了相应的抑制措施,并讨论了电磁兼容设计中需要注意的问题。

The electromagnetic environment of radar is very complicated,and the problem of electromagnetic compatibility is becoming more and more outstanding.A large quantity of switching-power supply is already applied in radar system,which requires that it does not produce too big interference and has certain anti-interference ability.The technology of electromagnetic compatibility of switching-power supply now becomes a hotspot for the research of power-supply for radar.The mechanism of electromagnetic interference in switching-power supply is analyzed in this paper and their suppressing methods are presented.A few key points of electromagnetic compatibility design are discussed.
