反激式开关电源传导干扰的Saber建模仿真

Saber Modeling and Simulation of Conducted EMI in Flyback Switching Power Supply

针对目前反激式开关电源传导干扰问题较为严重的现象,分析了反激式开关电源的工作原理以及电路产生传导干扰的原因。利用Saber软件建立了电路的传导干扰仿真模型,得到了电路的传导干扰仿真波形。通过软件仿真结果与硬件电路的传导干扰波形测试结果相对比,验证了模型的适用性。

For the conducted EMI problem in flyback switching power supply is more serious,the flyback switching power supply works and the reasons of conducted EMI are analyzed. By using the Saber software simulation model is proposed to build, and the simulation waveforms of the conducted EMI is obtained. Test of the conduction EMI waveform of the hardware circuit and comparison with experimental results the method is verified.
