Title (EN) BLOOD PROCESSING APPARATUS WITH DIGITALLY CONTROLLED LINEAR VOLTAGE REGULATOR FOR OPTICAL PULSES
(FR) APPAREIL DE TRAITEMENT DU SANG ÉQUIPÉ D'UN RÉGULATEUR DE TENSION LINÉAIRE À COMMANDE NUMÉRIQUE POUR IMPULSIONS OPTIQUES
Abstract:
(EN) The invention relates to apparatus for controlling the processing of blood into blood components, particularly components for stroboscopic LED light sources for centrifuges. A digital control circuit controls a high amperage linear voltage regulator. The voltage regulator charges a capacitor bank, which in turn powers LED light sources. The digital control circuit comprises an N-channel switched mode FET. The switched mode FET receives a pulsed digital signal from the microprocessor controlling the blood processing apparatus. A by-pass resistor in parallel with the FET allows most of the current to flow past the FET, thus minimizes heating of the FET. The performance of the FET, therefore, remains stable despite extended use of the apparatus.
(FR) La présente invention concerne un appareil permettant de commander le traitement du sang pour le décomposer en composants sanguins, en particulier en composants destinés à des sources de lumière à DEL à effet stroboscopique pour des centrifugeuses. Un circuit de commande numérique commande un régulateur de tension linéaire à forte intensité de courant. Le régulateur de tension charge une batterie de condensateurs qui, à son tour, alimente les sources de lumière à DEL. Le circuit de commande numérique comprend un transistor à effet de champ (FET) en mode commuté à canal N. Le FET en mode commuté reçoit un signal numérique pulsé provenant du microprocesseur commandant l'appareil de traitement du sang. Une résistance de dérivation en parallèle avec le FET permet à la majeure partie du courant de circuler au-delà du FET, ce qui réduit à un minimum l'échauffement du FET. Les performances du FET restent donc stables même en cas d'utilisation prolongée de l'appareil.
