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.
