The power quality industry has developed certain index values that help us assess the quality of service as it relates to distortion caused by the presence of harmonics. These values, or harmonic ...

Many continuous-conduction-mode PFC controllers use a nonisolated boost topology with average current-mode control. Examples of such controllers are the UC1852, UC1854/UC1854A/UC1854B family and the ...

This article is part of a multi-part series on how to identify, monitor, diagnose, and deal with harmonics in electrical power systems. Last month’s article discussed how to determine if current ...

Up to now, this series has primarily discussed the DC specifications of an ADC. Now, we will talk about AC specifications like distortion and noise in the ADC. Total Harmonic Distortion (THD) is, as ...

Researchers in Malaysia have published a study of total harmonic distortion (THD) reduction techniques in PV systems and claim to have found an holistic and systematic approach. The paper Advances in ...

Wait a minute. Let’s see if I understand this. (Here I’m channeling you, the puzzled reader, after you’ve grabbed me in the coffee break of a Filter Wizard lecture morning). The frequency of the n th ...
