ABSTRACT:
An electric device is provided as an interface between a permanent power source and an electrical appliance for maintaining the appliance, or a component thereof, in an operative state during a momentary power failure. The electric circuit includes an auto-transformer for increasing the induced back electric magnetic field voltage which is present in the line voltage of the permanent power source during a momentary power outage. The auto-transformer increases the induced back electric magnetic field voltage to a voltage level which is sufficient to maintain digital clocks or other low power-requiring components incorporated in an electrical appliance in an operative state during a momentary power outage.
