Appeal 2007-1052
Application 10/329,906
FINDINGS OF FACT
The following findings of fact are supported by a preponderance of
the evidence.
The invention
1. Appellants invented an integrated power conversion system (10) that
combines power from various sources to inject an alternating current (AC)
back into the mains voltage supply when excess energy is available.3
(Specification 4).
2. As depicted in Figure 1, the power conversion system includes a
plurality of power sources such as a photovoltaic array (10), a battery (14)
and an alternative power source (16) (e.g. a fuel cell or a wind turbine).
(Id.)
3. Each of the power source (10, 14, 16) is fed into a DC to DC
converter (24) that produces a corresponding converted input voltage (Id. 5.)
4. The converted input voltages are fed into a DC regulated link (26) that
produces a combined converted voltage. (Id.)
3 Appellants’ Specification indicates that it is known in the art to implement
an independent converter system to convert energy for each power source in
a multi source system to produce a common voltage level that may be used
to power a mains supply. Specifically, at page 1, lines 18-23 in the
background of the invention section, Appellants’ Specification states the
following:
Generally speaking, in conventional multi-source systems, an
independent converter system is implemented for each type of power
source such that the energy provided from each alternative source can
be converted to a common voltage level that may be used to supply
power to a mains supply or load.
