FINALLY!!! I have found the phenomenon that I have been trying to explain. Honestly I have searched and searched to find the issue that I am experiencing in my boost converter design. I never thought the term, forward recovery existed, reverse recovery of course, but this shows that in my case and generally with young engineers these days (I am not a young inexperienced engineer, I just haven’t worked on designing boost converters before) that they don’t understand component theory. Thank you for discussing this topic. I have seen people discuss using a snubber circuit but I feel this is a cop out because why waste energy absorbing it in a snubber when through correct design you can reduce the transients that threaten to destroy your switch.
Thanks for the reference. I watched this after watching Allen's diode reverse recovery demonstration on the A2AEW channel. Anyone that finds this video helpful should appreciate how Allen demonstrates the PN junction capacitance of various diodes on his oscilloscope. He also compares silicon and schottky diodes.
I find really really helpful your presentations especially because you are not showing the boring basics of electronics which are taught in any degree, but useful practical information (which need to be considered for a good design) and as well references to known magazines e.g. IEEE. Keep doing it ! Your topics are of high interest !
The “boring basics” as you describe are the factors that young engineers these days are missing in their understanding. It really pisses me off because people these days end up “designing” led flashers using an arduino!!! Sorry mate you’ve just hit my pet hate
@@buffplums no problem Chris. My point was that it is difficult to find advanced topics in UA-cam, but always the basics. I agree 100% with you: having strong basics is the fundation to strong advanced skills.
Thank you so much for this lecture. how about the Forward Recovery of Schottky diode? I know Schottky has a lower reverse recovery in compare with PIN diode. Does Schottkey has a lower Forward recovery in compare to PIN?
Real schottky diodes have neither forward or reverse recovery : these are bipolar effects, found in bipolar devices, where both electrons and holes are used to carry the current. I say "real" because in silicon carbide (SiC), most of the diodes are hybrid designs (Merged Pn-Schottky or Junction Barrier Schottky).

Thanks for comment and for sharing your experience.

Hi Catalin,
Thanks for comment and encouragement. Comments like yours keep me going.
Couldn't agree more.

@@catalin3407 sorry mate I shouldn’t be such an arrogant arse lol… I’m pretty much old school and things have changed for good reason I reckon
