Good morning Professor Alonso. Before I start, I would like to thank you again for the knowledge you are sharing. I have another question on this video. The controller has the current limit feature implemented inside. Do we need and external over current protection? I am under the impression that the current limit control of a dc-dc converter helps with current limit and over current protection. Thank you.
Hello, thanks for your comment. As I say in the video for some reason the shutdown pin of the UC1846 spice model does not work as expected. This is why we implemented the short circuit protection externally. In a real life application I think the internal circuitry of the UC1846 should be OK to do the same function
Thank you so much Professor Alonso, your videos are very helpful for me. I have read your articles about variable inductor. Is it possible to prepare simulation videos about variable inductor and wireless power transfer?
Dear Professor. The Power Converter is receiving a lot of technology of size reduction , but, what about the size reduction of input rectifier & filter? What the options of bulk capacitor reduction? The PFC & Voltage doubler, on Universal SMPS are the best aproach? Could you coment (by video explanation). Regards.
Thank you so much Professor Alonso for the work you are doing.
You are welcome. Thanks for your comment!
Thank you professor for sharing
Thanks!
Simulation files are available here: github.com/marcosalonsoelectronics/Qspice-9

Good day Professor, I am using the latest version of Qspice , but your models are giving singular matrix errors, please help.

Thank you for your comment and suggestion. There are several videos on variable inductors on the channel. Please, check the Magnetics playlist

Hello, thanks for your interesting suggestion
@@MarcosAlonsoElectronics And, what about those very small SMPS of 10MHz switching convertion?I wil be waiting. Regards.
Please simulate white tl431 and pc817 model
Thanks for the suggestion
