摘要
阐述反激式开关电源在工作中产生EMI传导骚扰的原因,分析了骚扰的根源和传播途径,提出对开关电源设计中在电路滤波设计方面来抑制EMI传导骚扰,并通过设计实例进行仿真.
Because of Flyback switching power supply working identity,the EMI conducted disturbance is very serious.In this paper,based on analyzing the ave of the spread abroad of EMI conducted disturbance,giving the EMI filter design technology to Flyback switching power supply circuit.The simulation analysis for EMI conducted disturbance suppression is implemented.
