Oct 26, 2023 at 7:05 comment added Verbal Kint @kam1212, please look at slide 29 of my seminar where you see that, at turn off, the leakage inductance diverts the energy stored in the magnetizing inductance, implying zero current in the secondary and zero also in the primary for a fraction of time. Keep in mind that this is a model and you cannot directly observe the magnetizing current unless you reconstruct it.
Oct 25, 2023 at 20:39 comment added kam1212 @VerbalKint I have a question regarding the coupled inductor. When is the switch turned off then will there be any practical current flowing in the primary??? Practically we don't have two inductors in parallel as shown at the primary side in the question, so no current should flow??? The diagram in the question shows a loop forming between the LM and the coupled inductor at primary, and It can be seen diagrammatically that current can flow in the loop. But How is this practically observed when we just have one single primary winding and nothing parallel???? plz help.
May 26, 2022 at 14:39 comment added Verbal Kint @Big6, hello, oui, if the diode wasn't there to block, then you would have currents simultaneously circulating in the primary and secondary sides. Thanks for the kind words, I always try to bring some modest scientific substance rather than just quickly answering without details.
May 26, 2022 at 14:25 comment added Big6 Thanks for the great answer, I always learn something new from your posts. One quick question, though. If the diode wasn't there, would the coupled inductor behave as a "transformer" in the sense that it will transfer power to the secondary right away?

Dec 18, 2021 at 11:06 comment added Verbal Kint Perhaps figure 2 of this document will answer your question?
Dec 18, 2021 at 9:51 comment added Antonio51 -- Just a question about slide 44, EMI radiation. In my younger years, I saw an "article" on how to assemble "transistor and radiator" so as not to emit interference to "the outside" but to "short-circuit" it to the ground. I think by inserting a special additional "shield". but impossible to find this article ... Do you something as this ?
