Title (EN) 3-WIRE MULTIPHASE UPS WITH BYPASS
(FR) UPS MULTIPHASE À TROIS FILS AVEC DÉRIVATION
Abstract:
(EN) The present invention provides an uninterruptible power supply (UPS) device (100) for connection of a 3-wire multiphase AC source (112) to a 3-wire multiphase load (114), whereby the UPS device (100) is provided for multiphase operation, comprising a converter part (116), which is connected to at least one power source (112, 128) and the load (114), and a 3-wire bypass (118), which interconnects the AC source (112) to the load (114), whereby the bypass (118) comprises a bypass switch (130), which comprises an independently controlled switching unit (140) for each phase of the AC source (112), and the UPS device (100) comprises a control unit (132), which controls the converter part (116) and the bypass switch (130), whereby the control unit (132) controls the bypass switch (130) to power one of the three phases of the load (114) directly via the bypass (118) by one phase of the AC source (112), and the control unit (132) controls the converter part (116) to power the remaining two phases of the load (114). The invention further provides an uninterruptible power supply (UPS) system (102) comprising multiple of the above UPS devices (100), wherein the UPS devices (100) are connected in parallel to the load (114).
(FR) La présente invention concerne un dispositif d'alimentation sans coupure (UPS) qui permet de connecter une source CA multi-phase à 3 fils (112) à une charge multi-phase à 3 fils (114), le dispositif UPS (100) étant utilisé pour un fonctionnement multi-phase et comprenant une partie convertisseur (116), qui est connectée à au moins une source d'alimentation (112, 128) et à la charge (114), et une dérivation à 3 fils (118), qui interconnecte la source CA (112) à la charge (114), la dérivation (118) comprenant un commutateur de dérivation (130), qui comprend une unité de commutation à commande indépendante (140) pour chaque phase de la source CA (112), le dispositif UPS (100) comprenant une unité de commande (132), qui commande la partie convertisseur (116) et le commutateur de dérivation (130), l'unité de commande (132) commandant le commutateur de dérivation (130) pour alimenter l'une des trois phases de la charge (114) directement par l'intermédiaire de la dérivation (118) par une phase de la source CA (112), et l'unité de commande (132) commandant la partie de convertisseur (116) pour alimenter les deux phases restantes de la charge (114). L'invention concerne en outre un système d'alimentation sans coupure (UPS) (102) comprenant plusieurs desdits dispositifs UPS (100), les dispositifs UPS (100) étant connectés en parallèle à la charge (114).
