Features

* necessary for building robust and compact interleaved PFC stages, with a minimum of external components. General Features
* Near
* Unity Power Factor
* Substantial 180 Phase Shift in All Conditions Including Transient Phases
* Frequency Clamped Critical Conduction Mode (FCCrM) i. e

Applications

* Interleaving consists of paralleling two small stages in lieu of a bigger one, more difficult to design. This approach has several merits like the ease of implementation, the use of smaller components or a better distribution of the heating. Also, Interleaving extends the power range of Critical Co
