摘要
分析了LinkSwitch单片电源中电磁噪声的产生途径,给出了共模、差模干扰的传播途径,对不同的干扰源提出了相应的抑制方案,并重新设计了输入侧EMI滤波器。经过仿真测试证实了所提出的电磁干扰抑制方案的有效性。
The common mechanism induced electromagnetic noise is analyzed, and the principle of eleetronmagnetic disturbance is given, which is applied in LinkSwiteh circuit. Based on different disturbance sources, the respective method is expatiated. EMI filter is also lately designed. Through the experiment results telified the validity of these method.
