L4985A/B and L4986A/B power-factor correction (PFC) boost converters from ST integrate 800V startup circuitry and additional valuable proprietary features. The built-in high-voltage startup capability ...
STMicroelectronics’ L4985A/B and L4986A/B power-factor correction (PFC) boost converters look to simplify design and enhance flexibility by integrating 800V startup circuitry and additional valuable ...
The definition of power factor (PF) is the ratio of the power drawn from the power grid (apparent power) to the power actually consumed in the load (real power). A power factor of ‘1.0’ is defined as ...
Over the past few years there has been a big push by some environmental agencies to have off-line ac-dc power converters include power-factor correction (PFC). It started with the European Union's ...
This circuit provides latching and high-speed overcurrent protection for power-factor corrected (PFC) boost converters operating at dc voltages to 380 V. Overcurrent damage of PFC front-end boost ...
International Rectifier has introduced what it claims to be the industry's first IC to integrate power factor correction (PFC) and ballast control in a single 8pin SO-8 package. The IRS2580DS Combo8 ...
The introduction of silicon carbide (SiC) diodes has been a welcome solution to the reverse recovery losses in continuous conduction mode (CCM) boost power factor corrector (PFC) converters. While SiC ...
