Patent ID: 7786616

Claim:
A system for providing uninterruptible, continuous and uniform AC electrical power to a load device, the system including: a generator coupled to a combined energy storage device; a rechargeable energy storage device coupled to the combined energy storage device; an AC controller device including an AC controller input adapted to be coupled to a utility-provided AC power source and an AC controller output adapted to be coupled to the load device for providing power from the utility-provided AC power source to the load device and adapted to be coupled to the combined energy storage device for providing power from the utility-provided AC power source to the combined energy storage device for charging the rechargeable energy storage device; a converter device coupled at a first end to the combined energy storage device, and adapted to be coupled at a second end to the AC controller circuit and the load device, wherein the converter device operates in an inverter mode and converts DC power provided by the combined energy source to AC power to be delivered to the load device when the utility-provided AC power source is not capable of providing adequate power to the load device, and when the utility-provided AC power source is capable of providing adequate power to the load device, the converter device operates in a rectifier mode and converts AC power from the utility-provided AC power source to DC power to be delivered to the combined energy storage device to charge the rechargeable energy storage device, and wherein when the utility-provided AC power source is not capable of providing adequate AC power to the load device, the combined energy source provides DC power that is converted into uninterruptible, continuous and uniform AC power to the load device, the combined energy storage device receiving the DC power from the rechargeable energy storage device, and power from the generator working in tandem.
