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 ...

By eliminating current sensors without sacrificing efficiency, researchers have shown a new way to build smaller, cleaner, and more reliable AC/DC power converters pointing to slimmer chargers and ...

In everything from onboard chargers (OBCs) and DC-DC converters in EVs to the AI power supplies in data centers to solar, wind, and other renewable-energy systems, fully digital power control is ...

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 ...

The digital control of switching power supplies is firmly established in everything from EV onboard chargers (OBCs) to power-supply units (PSUs) in AI data centers to renewable-energy systems that ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

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 ...

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 ...

A man died on Christmas Eve morning after he lost control on a wet road and crashed into a power pole in the Sacramento area, ...
