在本文中，调光和频率的稳定性，电流波峰因数（CCF）和功率因数（PF）的高强度放电灯与方波馈电的影响进行了实验评估。对于该评估，使用电阻来稳定灯。电阻随灯的阻抗而变化。调光和频率变化的影响，观察到两种类型的灯不同的标称功率。结果指示灯稳定的范围和灯变得不稳定的前沿值。CCF和PF保持接近于1，并且在应用的测试期间没有观察到声学共振。
In this paper, the dimming and frequency effects on stability, current crest factor (CCF), and power factor (PF) of high-intensity discharge lamps fed with square waveforms are experimentally evaluated. For this evaluation, the lamp was stabilized using resistances. The resistances were varied in function of the impedance of the lamp. The effects of dimming and frequency variation were observed for two types of lamps of different nominal powers. The results indicate the ranges in which the lamp is stable and the frontier values in which the lamp becomes unstable. The CCF and PF remain close to unity, and no acoustic resonances were observed during the applied tests.
