Abstract

The power saving uninterruptible power supply (UPS) has a first and second switches, an energy spared switch, a transformer, an automatic voltage regulator (AVR), a charger-and-inverter, a normal mode determination unit and an electric switch. When the utility power is stable, the first and second switches are connected together to supply the utility power to a load. At the time, the energy spared switch is physically disconnected with the utility power and the transformer and the AVR. Therefore, the transformer and AVR do not consume more energy of the utility power and the transforming efficiency of the UPS is increased.
