Abstract

The goal of this project is to develop hybrid DC and AC wall outlets for an efficient, flexible power interface. A DC plug standard is also proposed to allow DC devices to be safely powered by the outlet with the correct DC voltage for each device. The primary objective is to create a power outlet compatible with the proposed DC plug as well as NEMA 5-15 AC plugs, enabling the same outlet to power both types of load as needed. The outlet is intended for buildings and systems transitioning to an isolated DC grid to encourage DC development and adoption. Existing wall wiring will be given 48V DC and used to power these devices, avoiding expensive rewiring when retrofitting. The outlet uses an H-bridge topology to facilitate DC to AC conversion, a Boost topology to reach standard wall voltage, and a Buck topology for DC voltage applications.
