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 ...

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 ...

Modern electronic systems need small, lightweight, high-efficiency power supplies. These supplies require cost-effective methods to take power from the AC power distribution grid and convert it to a ...

A new reference design developed by ROHM Semiconductor uses a single microcontroller (MCU) to control both sides of the AC-DC power supply — the power-factor-correction (PFC) AC-DC converter stage and ...

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 ...

It is no secret that any equipment that either heats or cools is coming under great scrutiny as governments increasingly legislate efficiency standards. In particular, washing machines, air ...
