１項に記載の無停電電源装置。[Scope of claim for utility model registration] 1. AC that converts AC power into DC power - DC converter and DC that converts DC power into AC power -
In an uninterruptible power supply device comprising an AC converter and a storage battery that supplies direct current to the DC-AC converter when the output of the AC power source decreases or during a power outage, the battery is connected in series with the storage battery to affect the discharge current of the storage battery. An uninterruptible power supply device connected to a circuit that limits the charging current of the storage battery without charging the storage battery. 2. A circuit that limits the charging current of the storage battery without affecting the discharge current of the storage battery is composed of a parallel circuit of a constant current circuit and a diode, and the storage battery is floating-charged with an AC-DC converter having drooping characteristics. An uninterruptible power supply device according to claim 1 of the utility model registration claim.
