About This Webinar	We live in a world surrounded by electronic devices which use switched mode power supplies (SMPS). The demand for power switchers with high efficiency and low EMI grows for all designers. Taking a few rules into consideration it is possible to satisfy this demand with just a few simple analog filters. In this webinar session we examine SMPS from different points of view and consider multiple filtering methods to find out which is the most suitable and effective to our needs. A universal solution does not exist for all design. We will consider a few SMPS examples and the right solution for each situation.
About the Presenter	Lorandt Fölkel (M.Eng.), Würth Elektronik eiSos GmbH Business Development Manager for Energy Harvesting, FAE for Eastern Europe, Baltic countries, Russia and Turkey Lorandt Fölkel was born in Kronstadt (Brasov/RO) in 1967. He is an application engineer for EMI/EMC situation and switched mode power supply (SMPS) design for industrial- and automotive electronic applications. Lorandt is the company spokesperson for EMC seminars and has trained design engineers at more than 400 worldwide seminars since 2005. He demonstrates a clear understanding of EMC problems at the board level. With over 28 years of experience in electronic design, including 15 years in product management for passive components at Würth Elektronik eiSos GmbH, Lorandt has expertise knowledge in EMC, filter design and efficiency improvement for SMPS. After studying at the Transylvania University In Brasov (Kronstadt) he worked as a service engineer in consumer electronics for 9 years, followed by 4 years as a design engineer for EX (explosion safety) remote controllers. About the company: Würth Elektronik eiSos GmbH is a European passive component manufacturer who designs and manufactures EMC ferrites, inductors for power supplies, transformers for power converter, LAN transformers, connectors and assembly components, with offerings in design service and support at local FAE’s Worldwide.
Live Giveaway	After each webinar there is a quiz related to the respective session with 2 questions. For this session customers can win a set of three books: Trilogy of Magnetic ABC of Capacitors Trilogy of Connector Members who complete all four quizzes correctly will also be entered for a chance to win: Wireless Power Transfer Solution Kit To GO Terms and Conditions are Attached.

Q&A 9.
Why are Buck converters aggressive on the input, and boost on output?
Because of the topology. Non constant current flow.

Q&A 8.
Could you list some tell tale signs of incorrect inductor issues? Basically how would I distiguish between inductor issue and maybe circuit layout /capacitor or other problem? Use shielded inductor for storage, calculate correct value according to the D-Cycle and Ripple Current.

Q&A 7.
Would you use a Ferrite Bead as output filter of a buck converter? If yes, would you place more of the output capacitors before or after the ferrite in a PI-configuration?
I would focus for a Buck conv. for the Input filtering, as they are more noise there. A “PI” filter is welcome with using low ESR & ESL caps and also a low DCR ferrite bead like WE-CBF.

Q&A 6.
How would you measure the current in the inductor on the PCB? Do I need a shunt resistor?
Myself I’m using a wire soldered to the Inductor where I can use my current probe from the scope. Above a shunt resistor you can measure the DC current but not so accurate the AC current.

Q&A 5.
In a buck topology, what would mean a singing inductor ? (an inductor that makes some noise)
In some situation the SW freq generates harmonics which can be heard (audio noise).
