In the realm of modern lighting, energy efficiency is a paramount concern, driven by rising energy costs, environmental sustainability goals, and the global push for net-zero carbon emissions. Direct ...

Batteries are a part of our everyday life, and power everything from phones to gaming handhelds to laptops, but do those batteries use AC or DC current?

Abstract This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of ...

INA219 current sensor The INA219 is a high-precision current, voltage, and power sensor chip designed by Texas Instruments. It has embedded a shunt voltage measurement amplifier and a voltage ...

By limiting the rapid increase in fault current, fault current limiters (FCLs) reduce the requirement for complex DC circuit breakers (DCCBs) design in order to isolate faults. This paper presents a ...

Direct Current Microgrids: DC Proponents Say It’s the One Direction to Go The devices rising to the top of the modern and future economic and technological food chains are almost all DC, such as ...

Direct current (dc) intrusion, commonly caused by geomagnetic storms and stray currents generated during subway operation and high-voltage dc (HVdc) transmission, results in transformer dc bias, which ...

There are many ways to use an Arduino on a model railroad. These tiny, inexpensive, programmable computers can perform functions such as controlling signals, routing turnouts, and running animations.

Inductor current measurements using only a single dc link current sensor in an interleaved dc-dc converter is introduced in this paper. This technique is appealing for the interleaved dc-dc converter ...
