Light-emitting diode (LEDs) have a promising prospect because of its outstanding
advantages: 1) long lifetime, 2) environmentally friendly, 3) flexibility of color mixing, 4) high …

Based on a survey on over 1400 commercial LED drivers and a literature review, a range of
LED driver topologies are classified according to their applications, power ratings …

In this paper, an integrated double buck-boost (IDBB) converter is proposed as a high-power-
factor offline power supply for power-LED lamps. The IDBB converter features just one …

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 …

The high-brightness white-light-emitting diode (LED) has attracted a lot of attention for its
high efficacy, simple to drive, environmentally friendly, long lifespan, and compact size. The …

This paper proposes a new isolated single-stage single-switch power-factor-correction (S4
PFC) driver for supplying light-emitting diodes (LEDs) without electrolytic capacitor. In the …

This paper proposes a novel single-stage ac-to-dc light-emitting-diode (LED) driver circuit. A
buck-boost power factor (PF) corrector is integrated with a flyback converter. A recycling path …

High-brightness LEDs are considered remarkable lighting devices due to their high
reliability, chromatic variety, and increasing efficiency. As a result, a high number of …

In this paper, a single-stage LED driver is proposed for a street lighting system. Two boost
circuits that share a single inductor are formed by integrating the switches of a half-bridge …

An efficient driver circuit is proposed for light-emitting-diode (LED) lamps with a dimming
feature. The driver consists of a flyback converter in series with the dc-link. By processing …
