Abstract

The world of electrical power is undergoing a significant transformation, spurred by increasing demand for energy efficiency, renewable energy integration and technological advancements. For over a century, AC power was the dominant form of electricity distribution; it maintains efficiency over long distances and easily adjusts to different voltage levels. However, with the rise of distributed energy resources, controlled energy flows, and motor power recuperation for reduced system losses, DC microgrids have emerged as a compelling alternative.

This paper introduces DC microgrids, their implementation in industrial applications, and several Texas Instruments (TI) reference designs that help enable efficient implementations.
