Title (EN) WIDE VOLTAGE, HIGH EFFICIENCY LED DRIVER CIRCUIT
(FR) CIRCUIT DE COMMANDE DE LED À HAUTE TENSION ET À GRAND RENDEMENT
Abstract: front page image
(EN)An electrical circuit and method for driving light emitting diodes with a constant current via a high efficiency DC-DC converter controlled by a digital controller through pulse width modulation (PWM). The light emitting diodes may be powered by a variety of power sources including batteries, supercapacitors or ultracapacitors.
(FR)L’invention concerne un circuit électrique et un procédé de commande de diodes électroluminescentes (LED) à l’aide d’un courant constant, par le biais d’un convertisseur c.c-c.c à grand rendement qui est contrôlé par un contrôleur numérique grâce à la modulation de largeur d’impulsions (PWM). Lesdites diodes électroluminescentes peuvent être alimentées par diverses sources d’alimentation, parmi lesquelles des batteries, des supercondensateurs ou des ultracondensateurs.
