Abstract
The power saving uninterruptible power supply (UPS) has a transformer, an automatic voltage regulator (AVR), a charger-and-inverter, a normal mode determination unit and an electric switch. The transformer has a primary side and a secondary side. The primary side is coupled to an alternating current (AC) power source. An AC input terminal of the AVR is coupled to the secondary side of the transformer to acquire an inducted AC power source to regulate the inducted AC power source to output to a load. The charger-and-inverter is coupled to the secondary side of the transformer to acquire a recharged power source to convert to a recharged current. The normal mode determination unit is coupled to the AC power source and the battery to detect a power supply status of the AC power source and battery capacity, so as to further determine whether current operation is normal.
