Abstract/Summary
The Hybrid AC/DC House is a home prototype and student learning environment that distributes both alternating current (AC) and direct current (DC) power to improve overall energy efficiency, energy independence, and reduce carbon footprint. By powering AC loads from the AC bus and DC loads from the DC bus, the conversion losses between the two forms of power are minimized thus saving energy. Precise electrical sensing of both AC and DC portions of the system is essential for energy monitoring, control, and safety. The existing sensing system utilizes numerous physically bulky modules, each with their own communication protocol for transmitting the data. This project addresses the limitations of the existing sensing architecture by developing new custom sensor boards for both AC and DC measurements, along with a centralized sensor hub responsible for processing sensor data and transmitting it to the main controller via Single Pair Ethernet (SPE). Each individual sensor board was tested and characterized to verify accurate voltage and current measurement performance. The sensor hub likewise demonstrated correct operation of its analog‑to‑digital converters (ADCs) and UART communication interface. Preliminary results confirm both the functional correctness and reduced physical footprint of the redesigned sensors. Future work will focus on revising the sensor and hub PCBs to enable full system‑level testing and integration within the Hybrid AC/DC House.
