电子线路的电磁兼容性分析

Electromagnetic Compatibility Anaysis of Electronic Circuit

电磁兼容设计实际上是针对电子产品中产生的电磁干扰进行优化设计,使之能成为符合各国或地区电磁兼容性的标准产品。开关电源电路和数字电路中的时钟电路是目前电子产品中最主要的电磁干扰源,它们是电磁兼容设计的主要内容。在此以一个开关电源的电磁兼容设计过程为例进行电磁兼容性分析。

The electromagnetic compatibility design is the optimized design to electromagnetic interference which is in the electronic products, it becomes a product which conforms to various countries or the area electromagnetic compatibility standard. Clock electric circuit of switching power supply and digital circuit is the main electromagnetism source in the presented electronic products,They are primary content in electromagnetic compatibility design. Taking a switching power supply＇s electromagnetic compatibility design process to analyze on the electromagnetic compatibility.
