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 ...

The high prices of energy are leading to renewed interest in the more efficient motors driven by Variable Frequency Drives or VFDs. Many types of motors such as brushless DC motors, switched ...

AC/DC power-factor correction (PFC) rectifiers are hugely benefitting from GaN FETs. They have very simple topologies; The inductor is the only magnetic part and this is usually a constant-frequency ...

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 ...

Why is Power Factor important? The phase relationship between the ac-power-line voltage and current is related by a term called power factor. For a purely resistive load on the power line, voltage and ...
