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 ...

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.

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...
