POWER TRANSFORMATION SYSTEM
First Claim
1. A method for power transformation comprising:
- providing a rectifier having a first input terminal for connection to a first terminal of a power source, second input terminal for connection to a first terminal of a first load, and having first and second output terminals;
connecting an input of a first current source to the first output terminal of the rectifier;
connecting an output of the first current source to the second output terminal of the rectifier;
connecting an input of a second current source to the first output terminal of the rectifier;
connecting an output of the second current source to a first terminal of an ultra capacitor; and
connecting a second terminal of the ultra capacitor to the second output terminal of the rectifier; and
wherein;
the first load has a second terminal for connection to a second terminal of the power source;
the first current source has a control terminal;
an amount of current through the first current source is adjustable from zero to 100 percent of current available to the first current source from the rectifier, according to a signal to the control terminal; and
an amount of current available for the second current source is the current available to the first current source minus the amount of current to the first current source; and
current from the second current source, if any or all, goes to the ultra capacitor and/or a mechanism connected in parallel with the ultra capacitor.

Abstract
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.
