Title
(EN) AN UNIVERSAL POWER SUPPLY SYSTEM WITH LOAD ISOLATING AND VOLTAGE ENHANCE DEVICE
(FR) SYSTÈME D'ALIMENTATION ÉLECTRIQUE UNIVERSEL DOTÉ D'UN DISPOSITIF D'ISOLATION DE CHARGE ET D'AMÉLIORATION DE TENSION
Abstract
(EN) This invention relates to power supply system having recharging unit with load isolation and its method of operation. The power supply unit has one or more energy storage device and such energy storage device is of low voltage rating when compared with the operating voltage of the load. The power supply units when operated through an intermediate section and an output combiner, due to alternative parallel and series connections of capacitors supplies to the load an enhanced voltage as required by the load with complete isolation between the recharging unit of the system and load. The recharging unit supplies the recharging voltage to the input battery whenever the input battery is isolated from the load. Due to which, the energy storage devices serves for large distance range and better speed range in case of electric vehicles.
(FR) La présente invention a trait à un système d'alimentation électrique qui est équipé d'une unité de recharge dotée d'une isolation de charge et à son procédé de fonctionnement. L'unité d'alimentation électrique est pourvue d'un ou de plusieurs dispositifs de stockage d'énergie et ledit dispositif de stockage d'énergie est de faible tension nominale par rapport à la tension de fonctionnement de la charge. Les unités d'alimentation électrique, lorsqu'elles sont mises en fonctionnement au moyen d'une section intermédiaire et d'un combinateur de sortie, en raison des connexions en parallèle et en série alternatives des condensateurs, fournissent à la charge une tension améliorée comme requis par la charge avec une isolation complète entre l'unité de recharge du système et la charge. L'unité de recharge fournit la tension de recharge à la batterie d'entrée lorsque cette dernière est isolée de la charge. De ce fait, les dispositifs de stockage d'énergie permettent un fonctionnement sur une grande plage de distances et une meilleure gamme de vitesses dans le cas d'une utilisation dans des véhicules électriques.
