Abstract
A power server system includes a power transmission interface, a power supply and a battery backup unit (BBU). The power supply converts an AC power into a DC power and outputs the DC power to the power transmission interface. After the AC power is disconnected, the power supply continues outputting the DC power in a holding period having a rising period and a current sharing period. The BBU outputs a redundant power to the power transmission interface before the power supply stops outputting the DC power. The BBU boosts the voltage level of the redundant power in the rising period, and controls the voltage level of the redundant power to be the same with that of the DC power in the current sharing period, so that the battery output inrush current is reduced and the battery life is extended.
