US 2013/0159735 A1 · POWER MANAGEMENT SYSTEM AND METHOD

Abstract

A power management system of a server includes a power supply unit, and a power backup unit connecting to an input terminal and an output terminal of the power supply unit. The power backup unit further includes a charging unit, a power storage unit, and a converting unit. The charging unit uses an output power from the output terminal to charge the power storage unit when an external power source is supplying power to the power supply unit. The converting unit converts a stored power of the power storage unit to provide a backup power to the input terminal when the external power source is shutdown. The disclosure further provides a power management method.

and
a power backup unit, further comprising:
a power storage unit configured to store a second DC power;
a charging unit connecting the power storage unit to the power supply unit to charge the power storage unit by the first DC power when the external power source provides the first AC power;
and
a converting unit connecting the power storage unit to the power supply unit to convert the second DC power to a second AC power to provide the second AC power to the power supply unit when the external power source stops providing the first AC power.
