Zusammenfassung:	The utility model relates to a back-up power source. The primary side of a transformer is connected into an AC (alternating-current) power source, and the secondary side is connected into a bridge type rectifier circuit; and two parallel circuits, namely a compactor circuit and a battery and overcurrent and overload protection circuit, are respectively connected in parallel at the output terminal of the bridge type rectifier circuit. The back-up power source adopts an overcurrent protection system, therefore, not only quality is ensured, but also production cost is reduced.
