Title (EN) EMERGENCY POWER SOURCE
(FR) SOURCE D"ENERGIE DE SECOURS
Abstract: front page image
(EN)This invention relates to the field of emergency power sources which are automatically activated when ordinary utility power supplies fail, as during blackouts. More particularly, the invention relates to the field of emergency power supplies of the type containing a storage battery which is charged during normal situations and discharged as an emergency supply during power outages. The present invention is of the type that is designed to supply an AC load (43) under emergency conditions. Hence, an inverter is required to convert the DC stored in the battery (50) to AC. The emergency power supply (25) features a fixed phase shift (o) between the input (Es) and battery charging waveforms (Ei) and intermittent inverter operation under normal (i.e., non-emergency) conditions.
(FR)L"invention se rapporte au domaine des sources d"energie de secours actionnees automatiquement lorsque les sources d"alimentation en energie ordinaires tombent en panne, par exemple pendant les coupures de courant. Plus particulierement, des alimentations de secours du type contenant une batterie d"accumulateurs qui est chargee pendant les situations normales et dechargee comme alimentation de secours pendant les pannes de courant. La presente invention vise a fournir une charge en courant alternatif (43) dans des conditions de secours. Par consequent, un inverseur est necessaire pour convertir le courant continu stocke dans la batterie (50) en courant alternatif. L"alimentation de secours (25) se caracterise par un dephasage fixe (66) entre l"entree (Es) et les formes d"onde de charge de batterie (Ei) et le fonctionnement intermittent de l"inverseur pendant des conditions normales (c-a-d, pendant les periodes ou la source normale fonctionne).
