Title (EN) SYSTEM AND APPARATUS FOR SURGE ENERGY PROTECTION
(FR) SYSTÈME ET APPAREIL DE PROTECTION CONTRE LES SURTENSIONS
Abstract:
(EN) The present disclosure is directed to an apparatus (102, 300) for providing power to an outdoor unit (101) and suppressing undesired surge energy imposed on the apparatus (102, 300) from the outdoor unit (101). In one aspect of the present disclosure, the apparatus (102, 300) includes a voltage step-up circuit (129) that receives an input direct current (DC) voltage and produces an output DC voltage higher than the received input DC voltage. The apparatus (102, 300) further includes a surge energy protection circuit (131) coupled between an interface connector (250) on the apparatus (102, 300) and the voltage step-up circuit (131), where the interface connector (250) couples the apparatus (102, 300) to the outdoor unit (101). The surge energy protection circuit (131) passes the output voltage from the voltage step-up circuit (129) to the interface connector (250). The apparatus (103, 300) further includes a diode (218) disposed between the voltage step-up circuit (129) and the surge energy protection circuit (131). The diode (218) prevents undesired surge energy from passing into the voltage step-up circuit (129).
(FR) La présente invention concerne un appareil (102, 300) destiné à fournir de l'énergie à une unité extérieure (101) et à supprimer une énergie de surtension indésirable imposée sur l'appareil (102, 300) à partir de l'unité extérieure (101). Selon un aspect de la présente invention, l'appareil (102, 300) comprend un circuit élévateur de tension (129) qui reçoit une tension continue d'entrée et produit une tension continue de sortie supérieure à la tension continue d'entrée reçue. L'appareil (102, 300) comprend en outre un circuit de protection contre les surtensions (131) couplé entre un connecteur d'interface (250) sur l'appareil (102, 300) et le circuit élévateur de tension (131), le connecteur d'interface (250) couplant l'appareil (102, 300) à l'unité extérieure (101). Le circuit de protection contre les surtensions (131) transmet la tension de sortie du circuit élévateur de tension (129) au connecteur d'interface (250). L'appareil (103, 300) comprend en outre une diode (218) disposée entre le circuit élévateur de tension (129) et le circuit de protection contre les surtensions (131). La diode (218) empêche l'énergie de surtension indésirable de passer dans le circuit élévateur de tension (129).
