Power transformation system with characterization
View Patent ↗A power transformation system having a power stealing mode for powering a device indirectly through an electrical load connected to a power source and also has a characterization mode. The transfer of energy from the power source via the load may go undetected. The system may store energy from the load in an ultra or super capacitor. This energy may be used to power Wi-Fi and various thermostat applications, among other things, associated with HVAC and building automation and management systems. Energy from the load may be supplemented or substituted with energy from a battery and/or a buck converter. In the characterization mode, the system may obtain data relative to power usage of a load and determine a profile to identify one or more components and their operating conditions.
1. A mechanism for characterization of a load related to a thermostat, comprising:
an instrument for measuring load current versus time;
a plotter connected to the instrument for graphing a waveform of the load current versus time;
an analyzer connected to the plotter for analyzing the waveform to identify one or more components of the load; and
a diagnostics evaluator connected to the analyzer to determine a health of the one or more components; and
wherein:
a load current versus time measurement reveals what type of equipment is being monitored by the measurement according to a catalog or table of measurements, or signatures as indicated by the measurements, that are correlated with types of equipment;
revealing a type of equipment is a capability of a power transformation system that can instead divert energy from a load for at least partially operating a thermostat; and
a learning by the thermostat of the equipment enables the power transformation system to deal with an operation of a heating system relative to affecting flame quality.
2. The mechanism of claim 1 , further comprising:

the instrument for measuring load current versus time is an integral portion of a power transformation device; and
the instrument measures load current versus time when the power transformation is not harvesting power.
4. The mechanism of claim 1 , wherein:
the load current versus time measurement reveals a sequence of activity by the one or more components;
the sequence of activity can exhibit whether an operation of the one or more components is normal; and
if the one or more components have non-normal operation, then the load current versus time is analyzed to determine a basis or cause of the non-normal operation.
5. A method of a characterization mode of a power transformation system comprising:
providing an electrical waveform of power to a load related to a thermostat;
measuring a profile of the electrical waveform in terms of magnitude and time;
analyzing the magnitude versus time;

inferring a scenario of equipment from an analysis of the magnitude and time of the current waveform; and
providing a warning of a problem with the equipment from indications of a scenario; and
wherein:
the problem is indicated by the current waveform as there being no light off of a flame of one or more components of a furnace; and
the warning of the problem is provided before an extended or complete failure of a light off of the flame occurs.

11. The method of claim 5 , further comprising:
diagnosing the one or more components of the load from analyzing the magnitude and time of the current waveform; and
wherein if there is an issue of the one or more components of the load, there are identifying the issue from the magnitude and time of the current waveform, and searching for a solution to resolve the issue.
12. The method of claim 5 , further comprising:
facilitating a call for service to fix the problem with the equipment.
