TL;DR: A low-cost high-frequency power supply for ozone generation and the power supply stage is presented and analyzed, obtaining some important characteristics that allow the correct design of this power converter.

TL;DR: This work proposes the use of a current-fed bidirectional buck converter as a second stage, increasing the efficiency with respect to a conventional two stage topology and ensuring a constant current through the LEDs, and ability for AM and PWM dimming operation.

TL;DR: In this paper, an analysis of the series-resonant converters aiming to define a design methodology to improve the current ripple reduction provided by the SRC is proposed, and a discussion about the main factors that have influenced ripple reduction and the limits for this attenuation is presented, which have not been explored in the literature hither to.

TL;DR: This paper presents a high-power-factor LED driver implemented by using an input current shaper placed between the main rectifier and DC bus, and the use of a flyback converter operating as a loss free resistor provides reduced power processing, which increases overall efficiency of the converter.

TL;DR: The dimming and frequency effects on stability, current crest factor (CCF), and power factor (PF) of high-intensity discharge lamps fed with square waveforms are experimentally evaluated.
