ABSTRACT:
An alternating current power source which controls its own alternating current output through a feedback circuit which monitors the alternating current output is disclosed. The power source can be used as a backup to a primary power supply which provides power to a load. The present invention continuously monitors such primary power supply to detect power interruptions in the primary power supply. When an interruption is detected, monitoring logic circuitry of the alternating current power source disconnects the primary power supply from the load and energizes line driver circuitry of the present invention which provides the alternating current output. When the power interruption ceases, the monitoring logic circuitry reconnects the primary power supply to the load and disables the line driver circuitry so that alternating current is not provided by the present invention to the load. The alternating current power source includes an internal power supply which can be recharged through the line driver circuitry by the primary power supply when there is no power interruption in the primary power supply.
