If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: you can ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Discover how to build a simple device that converts light into electricity using LEDs and diodes. This step-by-step guide demonstrates assembling an LED-diode cluster, connecting it to a capacitor for ...

Abstract: The 2-kV photovoltaic (PV) system is widely regarded as the next evolution for megawatt-scale PV systems, enabling higher rated power. This article proposes a novel variable-level (VL) ...

Abstract: This letter proposes a unified concept of the active impedance module and its control method with minimum power processing. The impedance value and type of the proposed active impedance ...
