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 ...

Find a downloadable version of this story in pdf format at the end of the story. Until now, it was considered impossible to have an AC-DC converter with PFC and isolation features provided in a single ...

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 ...

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 ...

Interleaving isolated and nonisolated power stages is a well understood design technique within the power supply design industry. By far the most widely applied interleaved topology is the multiphase ...

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 ...

In this paper, the authors deal with a hybrid converter topology Power Factor Correction (PFC) for DC drives which is fed through a diode bridge rectifier from a single phase AC mains. In this paper, ...
