Title (EN) POWER SUPPLY APPARATUS
(FR) APPAREIL D'ALIMENTATION ÉLECTRIQUE
Abstract:
(EN) A power supply apparatus includes a rectifier configured to convert AC power supplied from an AC power supply into DC power, a smoothing unit configured to smooth the DC power, an inverter configured to convert the DC power smoothed by the smoothing unit into the AC power, and an abnormality detection unit configured to detect an abnormality. The smoothing unit includes a capacitor connected in parallel to an output of the rectifier, a discharge resistor configured to discharge the capacitor, and a switching device connected in series to the discharge resistor. The switching device is closed when an abnormality is detected by the abnormality detection unit, and the capacitor is discharged by the discharge resistor when the switching device is closed.
(FR) La présente invention concerne un appareil d'alimentation électrique qui comprend un redresseur configuré de sorte à convertir une puissance en courant alternatif fournie par une alimentation électrique en courant alternatif en une puissance en courant continu, une unité de lissage configurée de sorte à lisser la puissance en courant continu, un onduleur configuré de sorte à convertir la puissance en courant continu lissée par l'unité de lissage en une puissance en courant alternatif, et une unité de détection d'anomalie configurée de sorte à détecter une anomalie. L'unité de lissage comprend un condensateur raccordé en parallèle à une sortie du redresseur, une résistance de décharge configurée de sorte à décharger le condensateur, et un dispositif de commutation raccordé en série à la résistance de décharge. Le dispositif de commutation est fermé lorsqu'une anomalie est détectée par l'unité de détection d'anomalie et le condensateur est déchargé par la résistance de décharge lorsque le dispositif de commutation est fermé.
