| 摘 要： | 基于多涡卷混沌吸引子,提出了一种新型混沌PWM控制方法抑制电力电子变换器电磁干扰。该方法将多涡卷混沌吸引子与传统混沌PWM控制结合,应用于电力电子变换器的控制中,实现从电磁干扰源头上抑制传导电磁干扰。对比传统混沌PWM控制,该方法能够在降低开关频率及其倍数次谐波峰值的同时,减少开关频率及其倍数次附近次谐波的生成,具有更好的EMI抑制效果。

| Abstract: | In this paper, a novel chaotic pulse width modulation(PWM) technique is put forward to suppress electromagnetic interference(EMI) in power converters. This control method combine multi-scroll chaotic attractors and traditional chaotic PWM and is adopted to the control process of power converters, which can suppress the conducted EMI on EMI source. Compared with traditional chaotic PWM, the proposed PWM can reduce the amplitude of harmonics peaks distributed on switching frequency and its multiples, and avoid low-frequency noises and sub-harmonic noises at the same time, which have a better effect in EMI suppression of power converters. |
