The strict restrictions imposed both by mandatory regulations and by the recommendations contained in current standards have led to the fact that most commercially available LED ballasts nowadays use two-stage topologies. The first stage is intended

In this work, a new closed-loop control system is applied to a class-E resonant DC&ndash
DC converter with voltage clamp used for light-emitting diode (LED) supply. The proposed power topology was first described by Ribas et al. in a recent work

This paper presents a new topology based on a modified class-E resonant inverter used as an LED series current regulator. The proposed topology behaves as a controllable nondissipative impedance that adjusts the current flowing through the lamp. In t

Publikováno v: Sensors and Actuators A: Physical. 216:123-127

In the late years, magnetic nanoparticles are being increasingly used for biological analysis due to their good performance in both magnetic separation and magnetic detection. Recently, a novel method of superparamagnetic particle detection inspired

Power-Dependent Small-Signal Model for Fluorescent Lamps Based on a Double-Pole Double-Zero Transfer Function

Autor: A.J. Calleja, Javier Ribas, R. E. Diaz, D. Gacio, Manuel Rico-Secades, Jorge Garcia

Publikováno v: IAS Annual Meeting

In the prior literature, the small-signal incremental impedance of fluorescent lamps has been characterized using a single-pole single-zero transfer function. This transfer function provides a good estimation of the lamp dynamics at rated power. Howe
