- Chaotic switching signal obtained from chua ' s circuit was used to control buck dc / dc converter . by compared the power spectrum of input current between chaotic modulations and classical pwm , it demonstrate that chaotic switching modulations have good effect on spreading power spectrum , which can be used to reduce the level of emi and to improve emc of smps
通过对四种混沌调制模式下变换器输入电流与周期pwm模式下输入电流频谱的分析比较表明，混沌调制技术在扩展频谱方面有良好的效果，可以用于降低开关模式电源的电磁干扰( emi )水平，改善电磁兼容性( emc ) 。
