摘要:
随着电子设备高度集成化,高速数字印刷电路产生的辐射骚扰日益严重,电磁屏蔽方法可有效扼制辐射干扰噪声. 然而,电子设备外壳易产生孔缝泄漏,大大降低了其电磁屏蔽效能. 针对开关电源,探讨了原理,利用CST仿真软件对不同开孔情况进行比较,得到一般性结论,为辐射噪声抑制提供了理论依据.
Abstract:
With the high integration of electronic devices,the radiation harassment caused by high-speed digital printed circuits is becoming more and more serious,and the existing electromagnetic shielding measures can effectively suppress the radiation interference noise. However,the outer casing of the electronic device is prone to leakage of the aperture,thereby greatly reducing its electromagnetic shielding effectiveness. Therefore,this paper studies the switching power supply,first discussing its principle,and then using CST simulation software to compare different opening conditions,and obtaining general conclusions,which provides a theoretical basis for radiation noise suppression.
