Our discussion will start with a primer on swinging boost capacitor circuits, which have long been used both to produce voltages higher than the power supply and to provide negative power supplies.

There are several technical features required of capacitors used in professional audio and music applications. High-fidelity and noiseless audio-filtering features are necessary without any compromise ...

Vishay Intertechnology is extending its 193 PUR-SI series of miniature snap-in power aluminium electrolytic capacitors. There are now voltage ratings of 550V and 600V. The idea is to allow designers ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

Selecting power capacitors requires an analysis of dielectric materials. Aluminum electrolytic capacitors are polar devices that feature a high volumetric density but cannot withstand reverse voltages ...

The author writes occasionally here about restoring vintage electronics. Vintage equipment relies on many components to run properly. Let’s focus today on what capacitors do in this process. A ...

Although shunt capacitors offer several advantages at all voltage levels, those advantages come at a price. Not only must you purchase, install, and maintain capacitor equipment, you must be able to ...

This file type includes high resolution graphics and schematics. Transistors and ICs are considered active components because they change signals using energy from the power supply. Capacitors, ...
