Title: A POWER TRANSFORMATION SYSTEM
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.
