Abstract
DC grids verifiably have the potential to be a strong partner of
conventional AC grids, but safety elements for DC are few. Based on the
analysis of different fault scenarios, the requirements for overcurrent safety
elements for a bipolar DC microgrid in a TN and an IT structure are derived.
First, a safety device for SELV DC buses is developed using JFETs as the main
switches. Second, a self-powered, autonomous, and bidirectional approach for main
buses is supplied by an energy-harvesting step-up converter and a
microcontroller controls MOSFETs. Each section concludes with prototypes and
their associated experimental results.
