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 ...

An open source credit card sized DC/DC converter to convert up to 600 V to 24 V in a energy-, cost- and space efficient way.

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.

Abstract: The aim of this paper is to present a further approach for analyzing the air electric arc in low-voltage circuit breakers (LVCBs). In order to achieve that, a new simulation model and ...
