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 …

Energy storage devices are essential to provide voltage and frequency stability in renewable
energy sources, such as solar and wind. Due to operational requirements of distributed …

For high input voltage (>; 264 V ac) ac/dc applications, a buck power factor correction (PFC)
converter is a good choice because of its low output voltage, high efficiency, lifetime …

An improved buck power factor correction (PFC) converter topology is proposed in this
paper. By adding an auxiliary switch and two diodes, the dead zones in ac input current of …

Quadratic converters have the voltage conversion ratios of two cascaded converters, but
with fewer switches. They are not widely used, however, because they are generally less …

The cascaded connection of power converters extends conversion ranges but requires
careful consideration due to high component count and efficiency concerns, as power is …

This article proposes a systematic synthesis method to identify the optimum converter
topology for a specified voltage conversion ratio. This gain-oriented converter synthesis is …

In this paper a new technique to reduce the LED current ripple and storage capacitance in
high power factor (PF) off-line LED power supplies is investigated. The proposed …

A novel integrated buck-flyback nonisolated power factor (PF) correction (PFC) converter is
proposed in this paper. This new converter is an inherent integration of a buck converter and …

The goal of this work is to develop a smart light-emitting diode lighting system for industrial
and domestic use with several advantages over conventional systems, namely energy …
