摘　　要：以一个能产生混沌、亚超混沌与超混沌信号的电路为信号源,以Boost型DC/DC变换器为对象,研究混沌的性质(混沌、亚超混沌以及超混沌)对降低开关电源电磁干扰水平效果的影响。仿真结果表明:不同性质的混沌序列,有不同的降低Boost型变换器的电磁干扰水平的效果。Using the circuit which can generate chaotic, sub-hyperchaotic and hyperchaotic signals as signal source and taking Boost DC/DC converter as an example, this paper studies the effects of the properties of chaos such as chaos, sub-hyperchaos and hyperchaos on reducing the level of EMI (electromagnetic interference)of DC/DC converters. Simulation results demonstrate that different chaos sequences with different properties have different effects on reducing the level of EMI.
