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 ...

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, ...

All things related to power factor and power-factor correction. How it arises, the problems it causes, regulations old and new, and how to mitigate it. There’s a tendency to think of energy on the ...

Researchers develop a sensorless boost PFC method delivering near 0.9998 power factor and low distortion, enabling smaller and more reliable power supplies for consumer electronics. Single-phase power ...

How often are homeowners approached by a salesperson at the doorstep selling a device that can go in a wall and supposedly save energy or reduce the monthly electricity bill substantially? The ...

By their very nature, power factor correction capacitors are special devices that operate close to their dielectric breakdown limits — time, temperature, and peak voltage, all of which contribute to ...

International Rectifier, IR® introduced the IR115x family of µPFC™ power factor correction (PFC) ICs for a wide variety of AC-DC applications including lighting, LCD/PDP TV and game console Switch ...

A medical system employs a 1-kW, four-phase, interleaved single-stage PFC circuit that provides a regulated 150-V dc from a single-phase 115-V ac, 60-Hz power source. This regulator serves as the ...
