This work presents the study, development, design and implementation of a self-oscillating resonant converter, having as application the activation of LEDs. After a bibliographic review, aiming to evaluate the context of ...

Designing simple chaotic circuits with complex dynamic behaviors that can generate coexisting and hidden attractors has attracted much interest recently. In this paper, a new voltage-tunable Colpitts oscillator based on a ...

This work presents the design and analysis of an electronic system with universal input to supply a fluorescent lamp. The system includes a self-oscillating electronic ballast and an additional circuit which allows keeping ...

This work presents the analysis and design of the self-oscillating electronic ballast to fluorescent lamps detection. The electronic ballast must be able to detect and run lamps with different power ratings, according to ...

This work presents a design methodology and analyss of the selfoscillating electronic ballast used in fluorescent lamps. The self-oscillating electronic ballast is represented as a control system with a nonlinear behavior. ...

In the literature, existing Josephson junction based oscillators are mostly driven by external sources. Knowing the different limits of the external driven systems, we propose in this work a new autonomous one that exhibits ...

Circadian rhythms are self-autonomous rhythms generated at cellular level with a period close to 24 hours in constant conditions. They are present in diverse organism, from bacteria to mammals. Although they appear ...

This monograph deals with the design and implementation of a fluorescent lamp reactor, with luminous intensity control. The activation of the fluorescent lamp is carried out through a half-bridge inverter with resonant LCC ...
