Abstract
According to one disclosed embodiment, a smart power delivery system includes a power conversion unit having a communication module and a power management module that can convert mains power into an optimized voltage and limited current used to power an electronic device. In one embodiment, a power conversion unit can optimize an output voltage by communicating with a connected electronic device and exchanging parameters representing desired characteristics of the output voltage. In one embodiment, an electronic device receives power from a power conversion unit through a wired power conduit. In another embodiment, an electronic device receives power from a power conversion unit through a wireless power conduit. In one embodiment, an optimal voltage is selected after negotiation between multiple electronic devices and a power conversion unit.
