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/DC Boost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.

Abstract:

The level of electromagnetic interference (EMI) is related to the application of switch-mode power supply, and reducing the electromagnetic interference (EMI) level of switch-mode power supply is a hot issue in current research. Starting from the inherent chaotic phenomenon in switch-mode power converters, the idea of applying parameter combination control to change the working state to reduce the level of electromagnetic interference is proposed. Furthermore, the DC/DC Boost converter was used as the object to carry out computer simulation analysis. By adjusting the size of the parameters Iref, k and Vref, the transformer runs in periodic, quasi-periodic and chaotic modes, respectively. The simulation results show that the electromagnetic interference level of switch-mode power supply can be reduced without attaching any peripheral circuits by using the inherent chaos phenomenon in the switch-mode power supply.
