Server uninterruptable power supply

摘要

The server uninterruptible power supply is housed inside the server case (91), and is connected to the 12V DC power supply line (43) of the server. The uninterruptible power supply is provided with a DC/DC boost converter (3) that steps-up the power supply line (43) voltage to the rechargeable battery (1) charging voltage, rechargeable batteries (1) having a specified voltage of 13V to 60V, a DC/DC step-down converter (2) that steps-down the rechargeable battery (1) voltage to the voltage of the power supply line (43), and a charging and discharging control circuit (4) that controls the DC/DC boost converter (3) and the DC/DC step-down converter (2). In the event of commercial power source (95) outage, the uninterruptible power supply steps-down the rechargeable battery (1) output voltage to the voltage of the power supply line (43) and outputs that voltage to maintain operation of the server.
