Abstract

In this paper a new capacitor-less LED drive is proposed. The design is based on the utilization of the internal capacitance of the LED to replace the smoothing capacitor. LED lighting systems usually have many LEDs for better illumination that can reach multiple tens of LEDs. Such configuration can be utilized to enlarge the total internal capacitance and hence minimize the output ripple. In addition, the switching frequency is selected such that minimum ripple appears at the output. The functionality of the proposed design is confirmed experimentally and the efficiency of the drive is 85% at full load.

一种新型无电容LED驱动器

本文提出了一种新型的无电容LED驱动器。本设计是基于利用LED的内部电容来代替平滑电容。LED照明系统通常有许多LED，以获得更好的照明，可以达到数十个LED。这样的配置可以用来扩大总内部电容，从而最小化输出纹波。此外，开关频率的选择使输出端出现最小纹波。实验结果表明，所提出的设计的功能性得到了证实，在满载时，驱动器的效率为85%。
