摘要 电磁干扰(EMI)水平的高低关乎到开关模式电源的应用,降低开关模式电源的电磁干扰(EMI)水平是当前研究的热点问题.从开关模式电源变换器中固有的混沌现象出发,提出应用参数组合控制改变工作状态实现降低电磁干扰水平的思路.进一步以DC/DCBoost变换器为对象,进行了计算机模拟分析.通过调节参数Iref,k及Vref的大小,分别使变换器运行于周期、拟周期和混沌模式.所得模拟结果表明,利用开关模式电源中固有的混沌现象,通过组合参数控制可以在不附加任何外围电路的情况下降低其电磁干扰水平. The level of EMI is a performance index to the switchedmode power supplyHow to reduce EMI level of switchedmode power supply is an intensive issue at present.The idea that uses controlling parameters to change the state of the circuit to reduce EMI is presented by utilizing chaos inherent in the switchedmode power supply We take DC/DC Boost converter as a computer exampleBy changing the parameters:Iref,k and Vref,the converter is tuned to period,quasiperiod and chaos statesThe simulation results demonstrate that by controlling parameters EMI can be reduced without any additional circuits being involved.
