摘要
在工控系统或电子设备中,系统抗电磁干扰能力是衡量其稳定性或产品优劣的一个重要指标。电磁干扰主要通过电源使工频电网和系统内部发生双向的联系。本文在分析电磁干扰基础上,给出EMI电源滤波器的仿真设计方案及其应用注意事项。该方案设计的滤波器用于空调控制线路电源输入端,取得较好的效果。
One of the important specifications for electronic devices is its capacity of antielectromagnetic interference. EMI arises from the interaction between the AC power supply and electronic devices. Based on the analysis of electromagnetic interference, a new design and simulation of a anti-EMI filter for electronic device were presented, and the requirements in the application was suggested.
