Title:
UNINTERRUPTIBLE POWER SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/006329
Kind Code:
A1
Abstract:
This uninterruptible power source device (10) comprises: an input/output terminal (11) that is connected in parallel with a power source line (21) that supplies electric power from an external power source (20) to a loading device (30); a battery unit (12) that has a voltage rating that is lower than the voltage (V1) of the external power source (20); a DC/DC converter (13) that converts the voltage (V2) of the battery unit (12) to a voltage (V3) that corresponds to the difference between the voltage (V1) of the external power source (20) and the voltage (V2) of the battery unit (12); a charging circuit (14) that uses the electric power of the external power source (20) to charge the battery unit (12) via the input/output terminal (11); and a discharging circuit (15) that, when the power from the external power source (20) is interrupted, discharges to the loading device (30) via the input/output terminal (11) at a voltage that that is the voltage (V2) of the battery unit (12) plus the output voltage (V3) of the DC/DC converter (13).
