Abstract
An uninterruptible power supply system senses quality of available three phase input power and determines if load requirements can be met therefrom. If not, it drives an inverter to generate acceptable quality three phase AC to supply to the load. In this mode, the energy is obtained from a battery array. A solar panel can be used as a primary or a secondary source of input energy.
