摘　　要：以Boost型DC DC变换器为对象,研究在同一混沌调制模式下,不同混沌源对降低开关电源电磁干扰水平效果的影响。仿真结果表明:不同混沌源调制信号有不同的降低电磁干扰水平效果,Lorenz混沌源降低电磁干扰水平的效果较好。By taking Boost DC/DC converter as an example,this paper studies the effect on reducing EMI level of Boost DC/DC converter by different chaotic sources under the same chaotic modulation modes. Simulation results demonstrate that different chaotic signals have different effects. As far as chaotic (sources) are concerned, a concrete conclusion can be drawn that the effect of Lorenz system on reducing the level of EMI is better than the others.
