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

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

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 ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

Electric vehicles (EVs) use several kilowatts of energy to drive the ac synchronous propulsion motor from 400-V lithium-ion (Li-ion) batteries. The dc/dc circuits used to charge the batteries generate ...

The phrase power factor frequently is used in the electrical and power electronics industry. For example, home, office, and industrial electrical equipment often is fitted with power factor-corrected ...

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

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 ...

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 ...

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 ...

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 ...
