UNINTERRUPTIBLE POWER SYSTEM AND METHOD OF OPERATING THE SAME
First Claim
1. An uninterruptible power system comprising:
- a power distribution apparatus electrically connected to an external AC power, the power distribution apparatus comprising;
a plurality of power supply units configured to receive the external AC power and convert the external AC power into a first DC output power to supply a DC load; and
an interruptible power apparatus electrically connected to an external DC power, the interruptible power apparatus comprising;
a plurality of power conversion modules configured to receive the external DC power and convert the external DC power into a second DC output power to supply the DC load;
wherein the DC load is supplied by the first DC output power when the external AC power normally operates, whereas the DC load is supplied by the second DC output power when the external AC power abnormally operates; and
the external AC power and the external DC power are configured to separately and independently supply the DC load.

Abstract
An uninterruptible power system includes a power distribution apparatus and an interruptible power apparatus. The power distribution apparatus has a plurality of power supply units, which receive an external AC power and convert the external AC power into a first DC output power to supply a DC load. The interruptible power apparatus has a plurality of power conversion modules, which receive an external DC power and convert the external DC power into a second DC output power to supply the DC load. The DC load is supplied by the first DC output power when the external AC power normally operates; whereas the DC load is supplied by the second DC output power when the external AC power abnormally operates.
