A review of various proposed schemes to increase the reliability and life span of solid-state
lighting (SSL) systems is presented in this article. Since the mainstream devices employed …

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 …

A “one-and-a-half stage” forward-flyback converter for electrolytic capacitor-less light-
emitting diode (LED) driver with high power factor (PF), high efficiency, low output ripple …

Recent developments in improving lighting efficiency and cost reduction of LEDs have made
them suitable alternatives to the current lighting systems. In this paper, a novel offline …

This paper presents a new droop control method to reduce battery degradation costs in
islanded direct current (DC) microgrids for multiple battery energy storage systems (BESSs) …

We are almost always surrounded by light from LEDs in organic LED (OLED) TV screens
and active-matrix OLED displays in mobile phone screens. LEDs are everywhere, in …

An integrated non‐isolated DC–DC converter for applications that demand wide conversion
range is proposed in this work. Using a technique known as graft scheme, it is possible to …

This paper presents comparison of single-stage Single Ended Primary Inductance Converter
(SEPIC) and integrated SEPIC-Buck converter to drive Light Emitting Diodes (LED) in …

This paper presents an analysis of LED drivers applied to reduce low frequency current
ripple in LED loads. This current ripple is the result of the pulsing power at the input of the …

A charger topology using a single stage and transformer-less design employing bridgeless
semi quadratic voltage gain with high power factor (HPF) AC-DC converter, is demonstrated …
