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 …

This article proposes a feedforward voltage control strategy (FVCS), aimed to reduce the
output voltage double-line-frequency ripple and the output capacitance of the single-phase …

This article presents a modified asymmetrical half-bridge flyback converter (AHBFC) to fulfill
the single-stage step-down ac-dc universal input voltage application. This topology is …

Standard TRIAC-based dimmers introduce power quality issues especially for a large-scale
lighting network. Other existing dimming protocols involve additional wiring systems and/or …

In lighting system design, the LED light bulb technology is gaining more and more
advantages in comparison to other previous solutions. On the other hand, the designers of …

Recently, it has been shown that DC–AC and AC–DC power converters whose dynamics is
governed by two vastly different frequencies lead to a special class of piecewise smooth …

In this paper, a polytopic control approach is applied to a PV-fed single-ended primary-
inductance (SEPIC) dc-dc converter. In a clear-cut-contrast with conventional control …

In this paper, all operating modes of the ac-dc Cuk converter have been modeled as linear-
time invariant systems where some of the modes were not only modeled but also detected …

In recent years, direct current (DC) power supply loads have become more prevalent in
industrial and commercial applications. As a result, an ac/dc converting system will be …

The phenomenon of light emission in a PN junction is due to the recombination of electrons
and holes in the junction. This light emission phenomenon has been widely used in power …
