Determining power
First Claim
Patent Images
1. A method comprising:
- using a processing device for determining an amount of first power to supply to a load included in a system, using a relationship between a voltage provided by a power source to the system and a second power supplied by the power source to the system and using a minimum voltage value to be supplied to the system; and
measuring an amount of the second power;
measuring the voltage corresponding to the amount of the second power;
using the amount of the second power measured and the voltage corresponding to the amount of the second power in the determining the amount of the first power to supply to the load; and
supplying the amount of the first power to the load.

14. An apparatus, comprising:
-
a processing device configured to determine an amount of a power to be supplied to a load of a system from an AC mains using an expected change in a value of a voltage provided by the AC mains to the system that would result from supplying the amount of the power to the load; a device configured to provide an estimate of a second power supplied to the system by the power source, with the power corresponding to a first power; and wherein the processing device includes a configuration to determine a relationship between the value of the voltage and the second power; and wherein the processing device includes a configuration to determine the relationship between the value of the voltage and the second power during a time period corresponding to one or more of;
during first power up after installation of the system, periodically during operation of the system, a predetermined time period during a day. - View Dependent Claims (15, 16)

17. A method comprising:
using a processing device for determining an amount of first power to supply to a load included in a system, using a relationship between a voltage provided by a power source to the system and a second power supplied by the power source to the system and using a minimum voltage value to be supplied to the system, wherein the determining the amount of the first power includes accessing a look-up table specifying the relationship using a desired amount of the first power to determine a value expected for the voltage that results from supplying the desired amount of the first power.

18. A method comprising:
using a processing device for determining an amount of first power to supply to a load included in a system, using a relationship between a voltage provided by a power source to the system and a second power supplied by the power source to the system and using a minimum voltage value to be supplied to the system, wherein the first power is larger than the second power so as to compensate for impedance associated with the power source and so as to apply a second voltage to the load greater than the voltage.
