Wow, I've seen some poorly drawn schematics before, but this one is one of the worst !!! Thank you for translating it using the proper symbols, properly !!!

The bridge diodes at 3A DC out will see about 45A RMS, with top-wave spikes above 20A; not just 3A as stated

Sir, I am an electronics engineering student and I must say your videos helped me out a lot Thank you

Nice 👍👍

Nice

I love these types of videos

I love your videos because you explain the purpose of the chosen components and why they are there Over time I see the same patterns in lots of circuits and I can easily spot a voltage divider and rectifier bridge

Thanks for the video

Good job👍!!!

Nice but please, for God's sake, stop hiding everything with your hands all the time ! You always hide the only things we can see ! Use some kind of tip, it would be much nicer for your subscribers

thanks

I've got this power supplyhaven't got this schematic though

Theoritically speaking if you really wanted to use the 7805 could you hook up a 7812 in front of it you know conect the 12 output to the 7805s input would that do anything usefull would it even be a good idea?

BTW: I love these types of videos, you do a great job

Can you do a video explaining how to use balance resistors As often seen across diodes that are in series The series diodes are often used to increase the voltage handling capacity And they use resistors across those diodes to "balance" the voltages I would love to hear how this works and how to calculate them
Comment from : Little Clem

I really enjoy (and appreciate) the way you cover every detail in your videos Thank you and Keep up the great work!
Comment from : aerostar

Am I correct in assuming that you'll have to short the output to set the current limit?
Comment from : Vukuzenzele

How is the value of the capacitor after the rectification is calculated
Comment from : Jboy

Be careful if you change the 7824 regulator There can be more than 30 V on the input: Most 7812 can not handle 30V on the input, it is 24V i think, With a 24 V transformer you get about 34V
Comment from : Flemming Christiansen

Are you going to recommend a suitable transformer and fan to buy? It seems from the comments that a 24v fan would be best
Comment from : Robert Lundstrom

Don't forget that the resistor across the filter capacitor also serves to discharge the capacitor for safety reasons Although not really dangerous at this voltage, a capacitor can hold a high voltage for a long time unless discharged My linear amplifier takes almost 60 seconds to discharge the capacitors from 3700V to below 100V de WG2E
Comment from : Carl Wedekind

Even at 12v, the power dissipation in the fan regulator will become problematic A typical 12v fan will draw over 100ma which is over 2 watts, definitely will need to add a heat sink I used a small switching buck converter module to run a 12v fan
