Abstract: The arc current is essential for arc fault detection in power generation systems such as residential direct current (DC) microgrids and rooftop photovoltaic (PV) systems. However, the DC arc ...

Abstract: Since the arc-fault circuit interrupter (AFCI) was commercially introduced in 1998, questions have arisen about how it detect arcs, whether it detects series and parallel arcs, and what ...

A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist.
