High-Brightness Light Emitting Diodes (HB-LEDs) are considered the future trend in lighting
not only due to their high efficiency and high reliability, but also due to their other …

High-brightness light-emitting diodes (LEDs) are considered as a remarkable lighting device
due to their high reliability, chromatic variety, and increasing efficiency. As a consequence, a …

An improved twin-bus converter using n+ 1 active switches is proposed for the n-string LEDs
to be dimmable from true zero to the rated current level. The n-switches that perform the …

This paper presents a new control method and a detailed project methodology for the
optimized connection method of two converters, aiming to reduce the redundant power …

A novel power factor correction (PFC) cell, called flyboost, is presented. The proposed PFC
cell combines power conversion characteristics of conventional flyback and boost …

A study of the two-input post-regulators is carried out in this paper. In these post-regulators,
only a part of the total power undergoes a switching conversion process, whereas the …

In this paper, a single-stage (\rmS^2) parallel ac-to-dc converter based on single-switch two-
output boost–flyback converter is presented. The converter contains two semistages. One is …

This chapter presents an overview of various active harmonic reduction and power factor
correction (PFC) techniques applied in single-phase power supply feeding DC-DC …

This chapter presents an overview of various active harmonic reduction and power factor
correction (PFC) techniques applied in single-phase power supply feeding DC-DC …

Impending international standards on harmonic current levels drawn by single-phase mains-
operated equipment have created a need for low-cost off-line power-factor-corrected …
