But, somehow, Sorin you make things make better sense to me than any other professors, tutors, or texts can.

It's a nice build, really. For a home enthusiast, this is something nice to build and have. But, I'm wondering why you used the 10A fuse on the primary side (mains side) of the supply? With the power output of this supply, you can put the 1A fuse instead and be much safer. 1A fuse will blow when you've reached the 220-230W (mains voltage x the current). Also, use a slow-blow fuse because when you power on the supply, the transformer will draw a much larger current for a very short time. The 6A fuse on the secondary side is perfect.

Don't you think the Buck Boost converter will be more appropriate for this application and when transformer experiences a voltage drop, the back boost convert will adjust the voltage accordingly.
@Sorin_DIY
5 жыл бұрын
hi. the voltage drop appears at high voltage values and big loads. at medium and small voltages it has enough current, more than other power supplies and buck/boost converters. it's not a problem for me. buck/boost converters have their own disadvantages, most of them have a very low efficiency, 80% - 90%, and work with a lower current. you can find good buck/boost converters, with better efficiency and high current, but they are expensive. as for my power supply, I have some ideas to make it even more powerful. I will modify it in a future video.
