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.

EMC Standards is a world-leading resource for all things EMC and EMI related. Our website is packed full of both free and paid-for content, including:
- Online quiz
- Webinars
- Training quiz
- And much more!
Electromagnetic Engineering (EMgineering) is the basis for proven good design practices for signal integrity (SI), power integrity (PI), and the control of EMI emissions and immunity (EMC).
Our aim is to help people learn how to more quickly and cost-effectively design and manufacture electronic equipment (products, systems, installations, etc.) to meet functional (i.e. SI/PI) specifications and conform to EMC standards, directives and other requirements.
Such equipment should benefit from reduced warranty costs and financial risks, whilst improving uptime, competitiveness and profitability.
We also cover basic good electrical safety engineering; and the Risk Management of Electromagnetic Disturbances / EMI, whether for Functional Safety or other types of risk.
