灯电流波峰系数指标的优劣取决于电流波形。为获得具有普遍意义的分析计算方法 ,从几种典型的未调制波波峰系数的分析入手 ,先求得正弦 -正弦幅度调制波与波峰系数的关系式 ,进而推广到各种非正弦 -非正弦波相互调制的情况。为在电子镇流器的设计生产中有效控制波峰系数指标提供了定量分析的依据和手段
The pros and cons of the lamp current crest factor indicator depends on the current waveform. In order to obtain a universal analytical method, starting with the analysis of several typical unmodulated wave crests, the relationship between the sine-sine amplitude modulation wave and the crest factor is obtained first, and then generalized to various non-sinusoidal-non-sinusoidal Wave mutual modulation situation. Provide the basis and means of quantitative analysis for effectively controlling the crest factor index in the design and production of electronic ballast
