Light-Emitting Diodes (LEDs) are coming strongly into the lighting market due to their advantages over conventional lighting solutions: energy efficient, controllable in both light and color, long lifetime, lack of a warm-up period and high power density. Some of these advantages will make LED light sources to be more than just a lightbulb, being able to transmit data, control light color, hue and intensity or even detect people in indoor environments. Nevertheless, these advantages attributed to LED capabilities are, in reality, achieved thanks to the LED driver. The present work reviews the current stateof-the-art strategies to drive LEDs from ac power grids with special emphasis into removing the most limiting component from the point of view of the lifetime, which is the electrolytic capacitor, while achieving a flicker-free performance of the light output of the LED driver. Moreover, it focuses on analyzing the required regulations, challenges and applicability of LED drivers in both single-phase and three-phase ac power grids.Note: This only applies for certified dimmable luminaires.

“…It leads to a two-stage approach [1][2][3]. Many single-stage ac/dc LED drivers have been developed [4][5][6][7][8][9]. Among them, the basic converter such as boost converter, buck-boost converter or flyback converter can be adopted to perform the function of PFC.…”

This paper proposes a high-efficiency LED driver consisting of interleaved buck-boost and buck converters. With no need to use any auxiliary reactive components, the active switches can operate at zero-voltage switching on (ZVS). The buck-boost converter is operated at discontinuous-conduction mode (DCM) to perform the function of power-factor correction (PFC). The buck converter regulates the output voltage to drive LEDs. A prototype 60-W LED driver is built and tested. Experimental results show that the switching losses can be effectively reduced by operating the active switches at ZVS. The measured power factor and circuit efficiency are as high as 0.99 and 93%, respectively.I.

“…Charge-pump (CP) converters are considered single stage and have a reduced number of components because of this, they were widely used to drive fluorescent lamps. CP converters to drive power LEDs are shown in the works [1][2][3]. However, only fluorescent lamps using the bridgeless concept together with CP are presented in the literature [4].…”

A power factor correction (PFC) charge-pump (CP) bridgeless converter for LEDs is presented. In the input stage, coupled inductors, together with CP capacitors, are integrated into a half-bridge inverter, thus characterising the single stage. This topology even being bridgeless due to the positioning of the load operates with a bus voltage below the bending voltage. The CP configuration is used to reduce the LED's current ripple. The prototype achieves an output power of 60 W with high power factor, achieving the efficiency of up to 94%, 127 V ac input, total harmonic distortion of input current, with harmonic magnitudes within the IEC 61000-3-2 standard class C the device limits and flicker in conformed with the recommendation of IEEE 1789.
