What are harmonics in RF systems? A given signal’s second harmonic is approximately twice the given signal’s fundamental frequency. Ideally, amplifiers are expected to have zero non-linearities in the ...

The power quality of electrical distribution systems has a drastic effect on power regulation and consumption. Power quality includes all aspects of events in the power system that deviate from normal ...

Typically, harmonic distortion in the power supply isn’t addressed until it starts being suspected as a cause of equipment failure or downtime. Don’t be typical. Suppose you have two 480V motor ...

How to measure harmonics in a power system. Methodologies for reducing power system harmonics. A look at "triplen" harmonics. The IEEE standard 3002.8-2018, “Recommended Practice for Conducting ...

Musical instruments and throats create different notes by making the air around them vibrate at particular frequencies (check out part one to find out how they do it). When you pluck the A string on a ...

AC motors are abundant in the HVAC industry. Every fan and pump application requires an AC motor. For efficient and reliable control, adjustable-speed drives are becoming a common companion for these ...

Fifty years ago, Keldysh introduced an important idea. Treating both gases and solids on the same footing, he showed that strong-field ionization—valence-band to conduction-band transitions in ...
