Correction: At 16:02 there is a mistake in the figure at the top. The correct figure at the top should show buck mode on the left where Vi>>Vo, buck-boost in the middle, and boost mode on the right where Vi
Hello professor Alonso. This converter was my thesis in Mechatronic Engineering PoliTo, Master's Degree This topology is also called "Non inverting Buck Boost" because the polarity is not inverted, like in the classical buck boost It is a very useful circuit, but the layout is challenging
Thank you for the video! Very in dept lecture! I think i found an error: At 17.09, shouldn't it be an Efficiency - Vout - Diagram? It does not make sense to me, that when Vin increases it switches to boost mode. It should switch to Boost, when the required Vout is increasing, not? You also flipped the Buck & Boost zones in the above graph, compared to the previous slide.
Thanks for your comment. There is a mistake in the figure at the top. I don't know what happened here, some copy-paste issue probably. The correct figure at the top should show buck mode on the left where Vi>>Vo, buck-boost in the middle, and boost mode on the right where Vi
Hello, thanks your question. Note that with this converter you can send power to a load whose voltage can be lower or higher than the input voltage source. You can't do that with a SBC. SBC is bidirectional but the load that gets the power has to have a voltage that is always lower or always higher than the voltage of the source, depending on the direction of the power flow.
Hi Sir I am an undergrad and your work always helpful in all ways. I learnt LTspice only through your videos Sir. Sir I have a doubt ,Is there a way to do the simulation in LTspice and at the same time do the controlling part (coding part ) in matlab simultaneously both running at the same time to simulate a circuit. Is there a way to interface both ? or is there any other software do the simulation for Wide band gap devices and its application ?
Hello, thanks for your comment. As far as I know, there is no way to interface LTspice and Matlab. You can try the new simulator by Mike Engelhardt (the creator of LTspice). It is called Qspice and it allows you to add C++ code to the simulations. It is free to use too. You can download it here: p.qorvo.com/qspice-simulator.html. These are two introductory videos you can watch: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TN7_Q5fDvuE.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8QVFJBlTieQ.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-__ycmI0cdws.html We will deal with this new simulator on this channel in the near future... stay tune!
