Title
(EN) DUAL BOOST CONVERTER FOR UPS SYSTEM
(FR) DOUBLE CONVERTISSEUR ÉLÉVATEUR POUR SYSTÈME UPS
Abstract
(EN)
A power converter includes a power conversion circuit switchably coupled to a first power input and a second power input. The power conversion circuit is operable to generate positive and negative DC output voltages and is configured such that, in a backup mode of operation, the negative DC output voltage is generated using backup power through a first current path of the power conversion circuit that includes a first diode coupled between the second power input and a second DC bus, and, in a line mode of operation, the negative DC output voltage is generated using AC input power through a second current path of the power conversion circuit that bypasses the first diode and includes a second diode coupled between the first power input and the second DC bus.
(FR)
L'invention concerne un convertisseur de puissance comprenant un circuit de conversion de puissance couplé de manière commutable à une première entrée de courant et à une seconde entrée de courant. Le circuit de conversion de puissance a pour fonction produire des tensions de sortie continues positives et négatives et est configuré de telle manière que dans un mode de fonctionnement de secours, la tension de sortie continue négative est produite à partir d'une alimentation de secours, sur un premier trajet de courant du circuit de conversion de puissance, qui comprend une première diode montée entre la seconde entrée de courant et un second bus à courant continu, et dans un mode de fonctionnement sur secteur, une tension de sortie continue négative est produite à partir d'une d'alimentation de courant alternatif, sur un second trajet de courant du circuit de conversion de puissance qui contourne la première diode et comprend une seconde diode montée entre la première entrée de courant et le second bus à courant continu.
