The use of air-break disconnect switches to interrupt the capacitive currents associated with open‑ended bus runs and short lines is common practice. In most cases, the current magnitude is no more ...

Solid state lighting solutions are increasing in popularity across a broad variety of illumination, indication, signage and backlighting applications, replacing traditional incandescent and ...

Capacitive sensing finds use in all kinds of industrial, automotive, medical, and consumer applications. The popularity of this technology, especially in HID (human interface devices), has grown ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

In the conventional dc-dc converter buck topology (Fig. 1), power from the input voltage source is transferred to the output filter by turning on the pass transistor. When the pass transistor is on, ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

With digital twins (virtual replicas of objects or systems) of capacitors, engineers can simulate system-level interactions ...

Correctly installing capacitors at the terminals of your motors can lower reactive power requirements and increase system power factor. Induction motors are the primary source of rotary power in the ...

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...
