Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...

Two related phenomena, both called “power factor,” cause problems on electrical power lines. In each case, the ac current being drawn by the load is not exactly synchronized with the ac voltage on the ...

By eliminating current sensors without sacrificing efficiency, researchers have shown a new way to build smaller, cleaner, ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

Single-phase power factor correction (PFC) circuits--a kind of front-end AC/DC converters--are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what ...

Knowledge is power, allowing data centers to track and correct harmonics and power factor, avoiding costly energy waste, ...
