Patent ID: 7834480

Claim:
A distributed generation system connectable to an AC power line that provides AC electrical power from a source to a load, the distributed generation system comprising: a source of stored DC energy; a controller operative for: detecting line voltage and line current of the AC power line and for providing a first set of firing signals related to the AC line voltage and/or the AC line current, and detecting an amount of energy stored in the source of stored DC energy and for providing a second set of firing signals related thereto; an inverter connected between the power line and the source of stored DC energy and connected to receive the first set of firing signals from the controller; a DC power source; and a converter connected between the DC power source and the source of stored DC energy and connected to receive the second set of firing signals from the controller, wherein: the controller is operative for controlling the firing of the first and second sets of firing signals to deliver electrical power from the DC power source to the AC power line, or vice versa, via the source of stored DC energy; and the controller is further operative for controlling the firing of the first and second sets of firing signals to maintain the source of stored DC energy at a voltage greater than a peak AC line voltage and a voltage of the DC power source.
