ABSTRACT:
A parametric energy coupling system for providing uninterruptible a-c power o electrical loads. In a normal mode, a parametric transformer couples a-c line power directly from an a-c power source to a load. Upon a power outage occurrence, an inverter is energized whereby a-c power is generated from a d-c source and applied to the load.
