    This looks like a very nice project and the smps seems very stable and looks that it works fine. However if it had to be capable of delivering around 3 Amps of current it will be more useful to utilize as a bench power supply. I could not see from the video how it holds regulation of the output voltage with load. I guess it would be more appropriate to make a load test showing regulation and current draw at the same time. A view of the output ripple at load and off load will also help.

    Congratulations and thanks for posting your project.

    Regards Silvio

    Thank you very much. I will do that with a DC load.
