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 ...

Of course, there are countless value stocks that are worth mentioning, but this is a concise list of the top 6 undervalued ...

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 ...
