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 ...

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 have proposed a new way to control power factor correction circuits that could lead to sensorless power control.

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

Front end topology and some tips to design a mixed bridge circuit that effectively protects the design from an overvoltage. A robust solution using a new SCR generation and front end topologies that ...

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 ...

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 ...
