Power factor correction is a frequently misunderstood topic. Improper techniques can result in over-correction, under-correction, and/or harmonic resonance, so it can be helpful to understand the ...

There's always a besserwisser in the crowd and after receiving a couple of anonymous emails from one claiming to be an IEEE engineer, I brought together again, a collection of forces to help me better ...

If you've seen an Internet ad for capacitor-type power factor correction devices, you might be led to believe that using one can save you money on your residential electricity bill. However, ...

International Rectifier, IR®, a world leader in power management technology, announced the introduction of the IRS2500 µPFC™ power factor correction (PFC) control IC for switch mode power supply (SMPS ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...

PowerLogic PFC (previously knowns as VarSet), the low voltage power factor correction solution from Schneider Electric, expands its best-in-class low voltage capacitor bank with robust, IoT-enabled ...

A team of National Institute of Standards and Technology (NIST) researchers recently put out a white paper explaining why power factor correction type devices actually provide no savings to consumers.

Your utility Power Factor is the ratio of the system’s Real Power and the Apparent Power (Eq. 1, Fig. 1). This unitless factor ranges from −1 to 1. The Power Factor ratio aptly describes the type of ...

Most discussions on manufacturing energy efficiency focus on identifying easy-to-find-and-fix energy wasters such as compressed air leaks, inefficient lighting, equipment that is always left on when ...
