Patent abstract
An uninterruptible power supply (UPS) system includes a rectifier having inputs connectable to an input AC power line to receive AC power therefrom. The output of the rectifier is connected to the input of an inverter. A dual-purpose battery is connected to function as a battery boost when the rectifier is receiving AC power from the AC power line. If the UPS is switched to operate in battery mode, the battery provides input voltage to the inverter when the rectifier is not receiving AC power from the AC power source.
