考虑输入电流谐波与光闪烁特性的反激式LED驱动器滤波电容最小化研究

In this paper, a comprehensive study is conducted on reducing the size of output filter capacitor in an ac–dc flyback converter for driving high-brightness LED strings. To this end, a relationship between the input current harmonics, LED light flicker, and the magnitude of filter capacitor is obtained. It is shown that the size of the filter capacitor is mostly affected by the amplitude of the thi...
