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.
