Abstract

A smart power system is described. In one or more implementations, the smart power system comprises a microcontroller and a power converter electrically connected to the microcontroller and is configured to convert electrical energy from one form to another. The system also includes a switch element electrically connected to the microcontroller and configured to control distribution of the converted electrical energy to an electrical load. A sense element is electrically connected to the electrical load and to the microcontroller and is configured to monitor the converted electrical energy distributed to the electrical load and to furnish a feedback signal based upon the converted electrical energy. The microcontroller is configured to verify and to monitor the power converter, as well as to control and to monitor distribution of the converted electrical energy to the electrical load based upon the feedback signal.
