Designers have a choice between semi-bridgeless and interleaved PFC pre-regulators. The semi-bridgeless removes half the bridge-rectifier losses, whereas the interleaved PFC can reduce I2R losses up ...

A new interleaved three-phase PFC ac-dc single-stage multilevel is proposed in this paper. The Technical Session - Three-Phase AC-DC Converters Track: AC-DC Converters will be Wednesday, March 19, ...

Specifically designed for driving LEDs from a universal input range of 90 to 265 Vac, the LT3799 isolated LED controller offers active power factor correction and standard triac dimming, By using a ...

This design example report is a 16.75 W non-dimmable, high efficiency, power factor corrected, non-isolated buck LED driver employing LYTSwitch-1 LYT1604D. This design uses an input voltage ranging ...
