Abstract
An uninterruptible power supply to be connected between an AC line and a load has a battery system, an inverter, a transformer, and a controller. The battery system stores battery power. The inverter is operatively connected to the battery system. The transformer comprises a primary winding adapted to be connected to the AC line, a load winding adapted to be connected to the load, and an inverter winding operatively connected to the inverter. The controller controls the inverter to operate in a first mode in which the inverter supplies power to the battery system, a second mode in which the inverter supplies power to the load winding using battery power stored in the battery system, and a third mode in which the inverter supplies power to the primary winding using battery power stored in the battery system.
