Simplified power factor correction: Sensorless control could enable smaller, more reliable electronic adapters
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 ...
Providing power electronics design engineers with a convenient means of adding boost-type power factor correction to their switching power supplies, TT electronics BI Technologies offers a series of ...
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 ...
San Jose, Calif.—Renesas Technology's R2A20112 is a critical-conduction mode (CCM) power factor correction (PFC) control IC for AC/DC power supplies, which the company says is the first device of ...
Understanding power factor (PF) is important because it gives us a clear understanding of the efficiency of an electrical system. Put simply, it’s the ratio of true power and apparent power, which ...
How to design a ballast for integrated ballasts in compact fluorescent lamps (CFLs) that provide power factor correction (PFC) as well as normal ballast functions. The ballasts used in integrated ...
The relevant standard most power-supply designers follow for power factor correction (PFC) is the European norm EN61000-3-2. This applies to most off-line The relevant standard most power-supply ...
