Application 10/329,906
5. The combined converted voltage is fed into an inverter (28) that
produces an AC output current that is injected into a mains voltage (30).
(Id.)
The Prior Art Relied upon
6. As depicted in Figure 1, Lansberry teaches a grid-linked power supply
system having a plurality of power sources (21, 60, 40), each providing an
input voltage that is fed into a respective converter (10, 70, 50) to produce
corresponding converted input voltages. (Col. 5, ll. 1-22.)
7. Lansberry teaches that the converted input voltages are combined in a
circuit (77, 78, 79, and 89) that produces a combined input voltage. (Col. 5,
ll. 24-34; col. 6, ll. 5-9.)
8. Lansberry teaches that the combined input voltage is fed into an
inverter (80) that produces an AC current, which is fed to a load (100). (Id.)
9. Lansberry teaches that utilities companies have under-compensated
consumers that supplied excess power into the utility grid. (Col. 2, ll. 55-
58.)
10. As depicted in Figure 2, Fang teaches a plurality of power sources
(AC/DC PFC and DC/DC) that are fed into an inverter (40) to produce an
output voltage that is fed back to a reference generator. (Col. 5, ll. 9-13.)
11. As depicted in Figure 1, Emmerich teaches a utility company (12) that
supplies energy to a load (10) through an inverter (12). (Col. 3, ll. 36-45.)
12. Emmerich also teaches an energy storage (20) that provides an input
power to a converter to produce a converted voltage that is injected back into
the grid to keep the energy of the grid from falling below a predetermined
threshold. (Col. 3, ll. 8-23.)
