When capacitors are connected in series, the total capacitance is less than any one of the series capacitors’ individual capacitances. If two or more are connected, the overall effect is that of a ...

Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...

Ideal capacitors only exist in textbooks. Every real-world capacitor has additional complexity arising from its physical structure. Two plates separated by a dielectric layer are in series with wire ...

One of the most overlooked, but important performance characteristics of a capacitor used in power circuits is its equivalent series resistance (ESR). ESR determines the capacitor's I 2 R heating ...

Last month I talked about the problem of subsynchronous resonance (SSR) and the dynamic stabilizer as a solution. The stabilizer was basically an early thyristor-controlled reactor (TCR) device that ...

Vintage equipment relies on many components to run properly, Chuck Gloman writes. Let’s focus today on what capacitors do in ...

First, let's define a capacitor: It is an electromechanical device capable of storing electrical energy (electrons). It differs from a battery, as a battery produces electrical energy as a by-product ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...
