Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

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 ...

The world is moving toward greater use of power factor correction (PFC). Wild, Charles, Precision, Inc. - Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor ...

Choosing a capacitor for reliable performance in today’s automotive electronics requires an examination of several parameters. The performance characteristics of the various capacitor technologies ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

This file type includes high-resolution graphics and schematics when applicable. Low-power applications such as e-meters (electricity or energy meters) often require a simple ac line-powered supply ...
