摘　　要：对HPS灯声谐振时的等离子体现象进行了详细分析,并针对这一混沌现象,提出频率调制抑制技术。通过给扫频电路输入端叠加低频周期信号,从而消除声谐振时电弧抖动,同时评价不同扰动信号下声谐振的实际抑制效果,并给出抑制参数的选择方法、抑制电路及实验结果。实验表明,抑制电路能降低声谐振时电弧的抖动幅度,使得电弧由弯变直,最终消除声谐振现象。The plasmas phenomenon of Acoustic Resonance（ AR） in High Pressure Sodium（ HPS） lamps is analyzed in detail and frequency modulation technology is put forward to suppress the chaotic phenomenon of AR in this paper. The arc fluctuation amplitude is reduced by injecting low-frequency periodic signals into sweep circuit,so as to avoid arc fluctuation. Meanwhile,the suppression effects of AR are evaluated in different signals and the method of selecting suppression parameters,the suppression circuit and experimental results are given. The experiment shows that the phenomena of AR can be eliminated by using the suppression circuit which decreases fluctuation amplitude of arc and makes arc form from bend to straight.
