EMC design of Switching Power Converters Part 5 - Design techniques for LF (mains) rectifiers

The first possibility, is to use the type of converter described by Slobodan ─ćuk in that does not requirean input rectifier at all.

But if we are going to increase the cost of the Bill of Materials (BOM) by using a mains rectifier, we will oftenhave to further increase the BOM cost to deal with the switching noises and harmonic/interharmonic currentsit emits.
