The SSC2001S, developed and released by Sanken since 2012, is a continuous conduction mode (CCM) control integrated circuit (IC) designed for power factor correction (PFC). This device has a low peak ...

Most boost converters with PFC may operate in either discontinuous mode or continuous mode. In discontinuous mode (see the figure, a), the switch is turned on when the inductor current reaches zero ...

UCC28180 is ideal for universal AC input systems that operate in a range of 100-W to a few-kW, with the switching frequency programmable between 18 kHz and 250 kHz. It conveniently supports both IGBT ...

Some applications require a positive voltage to be generated from a negative input voltage. This can be done either by using a transformer based topology, such as a flyback converter, or with a ...

PNAS is the world's most-cited multidisciplinary scientific serial. It publishes high-impact research reports, commentaries, perspectives, reviews, colloquium papers, and actions of the Academy. In ...
