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 ...

Despite the name, electrical harmonics are terrible for data center harmony. In a perfect world, the power supply feeding a data center would produce a smooth, sinusoidal waveform at one constant ...

Harmonic is one of the most important concepts on the power system that cannot be neglected since it can affect the power quality and operation of equipment. High levels of Harmonics in the system may ...

Nonlinear VNA (NVNA) development has continued for more than 20 years, and many of the early researchers have remained involved. The result of various alliances and technical approaches is a group of ...

This article presents the use of PFC (Power Factor Correction) techniques as a means of improving power efficiency. This document briefly discusses the challenges of improving efficiency and its ...
