Filed:

May 31, 2000

Appl. No.:

09/583513

Inventors:

Christopher L. Dailey - Moyock NC

Assignee:

Innovations Electrical LC - Moyock NC

International Classification:

H02J 700

US Classification:

307 66, 307 43, 307 52, 307 80, 307 85

Abstract:

An auxiliary power supply system serves as a consumers primary power source during selected times and power outages in order to provide the consumer with a continuous supply of AC voltage. A power supply has a rechargeable DC source coupled to an inverter/charger circuit. A first switching means has an input port coupled to an AC voltage source and has an output port. The first switching means, programmable with at least one selected time period, couples the AC voltage source to the output port during a non-selected time period that is different than the selected time period and uncouples the AC voltage source from the output port during the selected time period. A second switching means is coupled to the output port and has a switch coupled between the output port and the inverter/charger circuit. The switch is selectively placed in one of a first position when a normal AC voltage is sensed and a second position when an inadequate AC voltage is sensed. In the first position, the switch is positioned to so that the normal AC voltage is available across the switch and is supplied to the inverter/charger circuit.

Abstract:

A power sharing system is provided for powering a plurality of loads using line voltage and a rechargeable source. Each load can be coupled to either the line voltage or the rechargeable source by means of a power source selector switch coupled to each load. A programmable controller is coupled to each power source selector switch to control a position thereof to maximize usage of the rechargeable source based on power requirements of the loads. The power sharing system can also recharge its rechargeable source during prescribed âoff peakâ times, and can provide power to the loads during times of power outages.
