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. </span></p><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;font-size:12pt;">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.</span></p></td></tr><tr><td style="border:1px solid black;border:1px solid #000000;padding:2px;"><span style="font-size:12pt;font-family:arial, helvetica, sans-serif;">About the Presenter </span></td><td style="border:1px solid black;border:1px solid #000000;padding:2px;"><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;font-size:12pt;"><strong><span lang="EN" style="color:red;">Lorandt Fölkel (M.Eng.), Würth Elektronik eiSos GmbH <br /></span><span lang="EN"></span></strong></span></p><p style="margin:0;padding:0px;"> </p><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;font-size:12pt;"><strong><span lang="EN">Business Development Manager for Energy Harvesting, FAE for Eastern Europe, Baltic countries, Russia and Turkey</span></strong></span></p><p style="margin:0;padding:0px;"> </p><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;font-size:12pt;">Lorandt Fölkel was born in Kronstadt (Brasov/RO) in 1967.

to everyone who has sent us your questions.</p><p>Lorandt has kindly provided Answers to these for you as follows:</p><p> </p><p>Q&A 1.</p><p>How does a saturated inductor affect performace, and everything else?</p><p><span>As soon as an Inductor saturate the EMI increase and the efficiency drop.</span></p><div style="clear:both;"></div>https://community.element14.com/learn/events/c/e/64Tue, 08 Mar 2016 09:59:26 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:b2eb5730-5551-4b65-a75b-d20c1e84039bjwatson<p>Q&A 2.</p><p>Are TI or Wurth making any fully integrated chips for ultra low power, IoT related applications?</p><p><strong><em>WE</em></strong><span> do not produce any chips right now. TI has in the portfolio few low power Energy Harvesting DC/DC controllers but not fully integrated.</span></p><div style="clear:both;"></div>https://community.element14.com/learn/events/c/e/64Tue, 08 Mar 2016 09:59:49 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:dcb70ff0-8e05-4d08-ba8c-73a840562760jwatson<p>Q&A 3.</p><p>How does the switching frequency effect the efficiency?</p><p><span>As soon the SW freq is higher, there are more core losses and skin- and proximity-losses .</span></p><div style="clear:both;"></div>https://community.element14.com/learn/events/c/e/64Tue, 08 Mar 2016 10:00:16 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:bfdc75d4-d9f2-4e07-946b-2c5cfd6fb05djwatson<p>Q&A 4.</p><p>Does the RedExpert SEPIC Converter calculator provide correct DC loss results when a feed-forward architecture is used?</p><p><span>Yes, the RedExpert is based on measured values.</span></p><div style="clear:both;"></div>https://community.element14.com/learn/events/c/e/64Tue, 08 Mar 2016 10:00:38 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1dce1559-9204-4655-8099-d0562769de84jwatson<p>Q&A 5.</p><p>In a buck topology, what would mean a singing inductor ? (an inductor that makes some noise)</p><p><span>In some situation the SW freq generates harmonics which can be heard (audio noise).</span></p><div style="clear:both;"></div>https://community.element14.com/learn/events/c/e/64Tue, 08 Mar 2016 10:01:01 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1745fad8-6490-4c77-a1c5-5a185a3061eajwatson<p>Q&A 6.</p><p>How would you measure the current in the inductor on the PCB? Do I need a shunt resistor?</p><p><span>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.</span></p><div style="clear:both;"></div>https://community.element14.com/learn/events/c/e/64Tue, 08 Mar 2016 10:04:08 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:e608aff0-f947-4e17-ab40-e05b26003249jwatson<p>Q&A 7.</p><p>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?</p><p><span>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.</span></p><div style="clear:both;"></div>https://community.element14.com/learn/events/c/e/64Tue, 08 Mar 2016 10:04:56 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:5148aa00-1f7b-448e-8a26-c327b6490fe8jwatson<p>Q&A 8.</p><p>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? <span>Use shielded inductor for storage, calculate correct value according to the D-Cycle and Ripple Current.</span></p><div style="clear:both;"></div>https://community.element14.com/learn/events/c/e/64Tue, 08 Mar 2016 10:06:20 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:7255d7a4-bb45-4781-8fff-8b51e7d028b2jwatson<p>Q&A 9.</p><p>Why are Buck converters aggressive on the input, and boost on output?</p><p><span>Because of the topology. Non constant current flow.</span></p><div style="clear:both;"></div>
