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 ...

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 ...

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 ...

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.

Over the past 40 years many of my designs included Power Factor Correction (PFC) ranging from 50 W to over 5.0 kW and operating from 30 kHz to 150 kHz switching frequency, utilizing CCM, CrCM and DCM ...

Understanding power factor (PF) is important because it gives us a clear understanding of the efficiency of an electrical system. Put simply, it’s the ratio of true power and apparent power, which ...

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 ...
