At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

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 ...

The project was built and designed to measure the quality of AC voltage using a harmonic distortion meter based on PIC18F2550. The project was built and designed to measure the quality of AC voltage ...

Tektronix must have been quite a place to work back in the 1980s. The company offered a bewildering selection of test equipment, and while the digital age was creeping in, much of their gear was still ...

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 ...

Arteche PQ, Inc. has introduced a complete range of active harmonic filters. This new filter product line achieves 5% total harmonic current distortion (THD) by monitoring the flow of harmonic ...

Figure 1a illustrates a typical transformer having a primary to secondary turns ratio of 1:N and a primary inductance of L P. In the real world, however, transformers aren't ideal, and they can become ...

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 ...

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 ...
