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, ...

Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor power factor will result in increasing electrical efficiencies and will reduce the overall use of ...

Most applications that use power factor correction (PFC) are mandated by regulatory requirements like the IEC1000-3-2 harmonic reduction requirement in force since January 1, 2001. The regulation ...

Power factor correction is a frequently misunderstood topic. Improper techniques can result in over-correction, under-correction, and/or harmonic resonance, so it can be helpful to understand the ...

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 ...

• Electrical power sources supply two types of power to inductive loads: real power in kW and reactive power in VAR. • Power-factor correction circuits can be either an individual style or of the bank ...

Until recently, power factor and PFC (power-factor-correction) circuits were of concernonly for utilities and manufacturersof motors. Utilities have for years specifiedthe power-factor performance ...

This application note describes the concepts and design of a boost preregulator for power factor correction. This note covers the important specifications for power factor correction, the boost power ...
