I am the opposite I find mechanical engineering so confusing and amazed how you make gears and leavers work especially when small and complex. But I look at electrical thing I get it. I’m a plumber but love electronics, but struggle with mechanical stuff. I think we all just have our brains wired a certain way
A lot of EE's wish they could do your type of work too. You bring ideas to life. We just add the sensors and actuators. We can't draw anything but a schematic, and we're always using templates if we're going old school, however it's common for us to draw free hand on a napkin. Thats often done over a beer or two or six or twelve.
You've somehow made power supply design less of a "voodoo magic" and just "dark arts". I'm subscribed and can't wait to see what other explainers you can illustrate so clearly!
Holy cow, so this is what they mean by "RUclips University"! Please keep making videos like this! Your ability to explain complex topics through the lens of real-world practicality is extraordinary. Not one concept in this video feels arbitrary, and that's a massive achievement given the topic at hand - so refreshing!
I have taken courses in feedback control and power electronics, but I never fully appreciated the awesomeness of these open and closed-loop regulators until now. Thanks for sharing!
You do go the extra length teaching electronics, and I highly appreciate that. As mentioned below, the individual PCBs move was genius, please keep'em coming. Kudos from Brazil.
I was a teenager in the early sixties. I had an inquisitive mind and was fascinated by electronics. Back in those days, the best I could manage to build and, to some extent, understand, was a crystal set AM radio receiver, and various simple audio amplification circuits using valves and speaker output transformers. The thing is, I barely understood what I was doing. With RUclips videos like this linear power supply build, today's young (or older) electronics enthusiasts are incredibly privileged. Thank you . I have subscribed and will now explore your other posts.
A first-class demonstration of a linear power supply. By explaining the function of components and why using them achieves an efficient and constant DC output. Plus their relationship to the complete circuit diagram. Thank you for the video.
Excellent introduction for the beginner. Thank you for not overwhelming new students with all the peripherals that go along with more the complex power supply. Perfect!
As an amateur radio ham who needs to have a basic grasp of electrical circuits & principles I found this block by block explanation absolutely captivating. Whilst I have been lucky to have some very talented mentors your practical demonstration coupled with explanation of the relevant technical terms and an oscilloscope has helped to strengthen my understanding. Thank you.
Well as a former trainer, i keep assessing delivery of information by presenters. You are better than all trainers I had, as you are not standing in a class in front of me and i was able to follow every step. I only wish my math teacher was that good. Now to the electronics piece, i am a ham radio operator and i want to build my own power supply now. I am following.

Coming soon (possibly next video). I already have what I hope is a really nice way to explain the three fundamental converter topologies. But I am busy with work and have a long term project I need to work on so may be a month or two I'm afraid.
SO nostalgic! I was building & designing linear PSUs as a teen, starting back in the early 80s. I built SO MANY 5V/5A PSUs for bareboard Ohio Scientific Superboards, which were about the cheapest 6502 based systems you could buy at the time.
this is youtube at it's best! randomly stumbled upon this video and even though i'm +20y in the business I found this modular system very cool and probably very easy to understand for beginners. Choosing the right video-thumbnail definitely adds up. Keep it going! watched til the end. You're an amazing teacher, I couldn't teach like that. Respect!
Excellent presentation. Retired electrical engineer from the Defense industry, I also taught electrical engineering courses to civilian and military personnel at various times. I'm impressed with your straightforward, careful and pretty thorough coverage using not only the hardware elements/components, but showing the various schematics as you progressed, along with the differential equations as appropriate.

This is great information. I've seen other explanations that skip over things assuming you know them already. This on the other hand covers every aspect. Nothing skipped over. Subscribed.
Wonder full video! In the end of the 80's at an age of 16 we broadcast every Sunday on FM 104,5 MHz with a self build FM transmitter and linear's, but there was nothing better in power supply then ordinary 12V car batteries🙂What ever we tried, during broadcasting on a unexpected moment noise came through with whatever we tried to build as a power supply. After so much thyristors, capacitors etc. we gave up, loaded the car batteries on Saturday and hoped they would last our 4 hours broadcasting. In those days it was illegal but accepted by local authorities for we made our entire small-town happy without any commercial gain. But to summarize, in self build FM broadcasting equipment our experience for the biggest obstacles were the antenna (my god the time spend on those antenna's...) and the power supply. Everything in between was easier to be done! The power supply in your fantastic video on the left at 0:57 is so recognizable! I see that *** thyristor in the right side exactly in the form as we tried using in our days! So now I'm curious how on earth it is possible that the power supply next to it on the right supplies the same 100% straight-line DC power, as you mentioned, can be found in another video. Keep up the good work, it refreshes (or reboot) technical knowledge in (old) old-school hobbyists like us!
WOW! I am a 40 year old studying electricity/electronics for the magic that it is. I am not ready to talk about transformers yet (still studying what is actually Flux) but this video gives me something to look forward to! I would like to play with power electronics but probably do miniature learning circuits, using human-safe batteries, not mains, to create a "demo AC" and then I am thinking I'd wind my own transformers to experiment and truly understand the effects (as far as we can understand them).

This is a phenomenal video. Your breakdown and explanation of the components and principles along with the visuals is so, so good. This was my first video, but you’ve definitely earned a subscriber. I wish there had been explanations this good 35 years ago when I was trying to get an EE degree.

I always ask the question of a video, is this guy just showing off, or is he 'spilling the beans' ? This is bean spilling at it's very finest, fantastic! Therefore, many thanks, much appreciated, and in addition, you have made the world a better place :)
The relationship between primary and secondary voltages in a transformer is certainly more than meets the eye. Thank you, thank you, I’ll be here all night. As smooth as his rizz. 😂😂
Absolutely amazing explanation! I have built power supplies before, but have never seen such a clean explanation. Kudos! You have earned another subscriber
Congratulations, you have done a brilliant job in all regards. Your explanations are technically sufficient without being overwhelming. The design of your components provides a visually appealing demonstration without the clutter of a breadboard.
Thanks! I agree, breadboards are great for prototyping and are understandable if you’re the person who build the circuit but trying to work out someone else’s circuit on a breadboard is so painful lol
Hi, an electrician here. The reason why some fuses have sand in them and some do not is because of what we call "rupture current". A fuse "blows" over a certain amperage, but litteraly "ruptures" or "explodes" at a far higher amperage. The basic theory is that you need higher and higher rupture-current components, the closer you get to the power source. Sand-filled fuses are usually designed to have a far higher rupture-current than an air-filled ones. If you wanna know more, read into "short-circuit current theory". 😉
One of the best teachers on youtube and being an excellent teacher is the highest accolade I can bestow because my teachers have been pivotally important, and positive influences throughout my entire life. SUBSCRIBED!
This is so damn well put together wow. Extremely helpful in understanding these seemingly simple components on a deeper level and how they play together. Thanks for this excellent and informational resource!
Fantastic tutorial on linear power supplies. I grew up when almost every appliance used a linear supply with discrete through hole components, there was even still a fair bit of vacuum tube tech kicking around in the eighties. It made things pretty easy to understand and work on, although you had to be careful working on things like CRTs while powered up so if you were serious about poking around in stuff an isolation transformer was often the second project you built after a linear bench supply to reduce the risks a little.
Where were you a year ago when I was trying to piece this info together for myself? Seriously, these videos are amazing and will absolutely be a boon to the next generation of EEs. Kudos.
Am a 2nd year electronics engr student, this was our first technical project and am currently designing and building one. Your video helped a lot, thankyou very much!
Fascinating. I have subconsciously been looking for a site like this for a long time. I have seen others where parts are explained in isolation but you provide a much clearer idea here. Helps that there was no distraction like music or memes or attempted comedy ... well very little. And the site you reference for parts is amazing, who knew? Not me anyway. More power to you ... heh heh.
I studied linear rectifiers almost 23 years ago, this is exactly how i was taught in my polytechnic. Nicely explained without any complicated math involved, outstanding video!
Your videos could not be more perfect! They’re extraordinary! The Lego-style explanations are brilliant. Side note: it would have been really nice to have mentioned possibly needing in inrush current limiter to prevent smoking the rectifier diodes when your smoothing capacitor gets “too big”. So looking forward to more of your content! Keep up the great work.
Speaking of Lego style, mad props to China for making a Lego brick out of every conceivable electronic functional unit in a way the West never provided and possibly never would have provided, to keep people as foolable as possible. (Like it does with news and other information)
@@paulchamberlain7942 Actually, back in 1970, I was given a collection of books and components from a correspondence course in electronics. It was even more like lego, tbh, and had all the components on plastic carriers that could be intereconnected to build just such circuits as these. It's not a new concept, but it is well done in this instance, to be sure.
I love your way of explaining this and especially breaking down the components into their own discrete module and plugin them in as you go. Keep it up mate.
This is simply amazing, could you do the same for switch mode power supply please, I know you already made a video on it but this method of building in real time and explaining is simply unmatched, once again thank you so much for make quality content like this.❤
It is much harder to do something like this for a switching converter because they are much more sensitive to the parasitic that are introduced in the connections. But I will be doing things like this again
Thank you for this incredible video! This is amazing yet so simple to understand! Now i know why i have components in power amp in such order and what is going on in that chain when it’s on. Incredible job to make people little bit more educated!
Great video, love those modular boards you made, really clearly explains how everything goes together! I'm a bit of a noob to electronics, I have used linear regulators before but haven't used open or closed loop ones, I will definitely read up more on it and experiment - thanks!
By far your best Video ive seen yet. All of them i learn something useful. Or it fills in a gap ive missed along the way from other channels. Ive git a new FAV now. YOU.
Years of interest in the field just to finally understand circuits are basically jumbled in a non linear compact cluster or they get put in a straight line to actually make arithmetic sense. Where has this been my entire college education. This put half of my studies into one episode and actually made enough sense.
I was pleasantly surprised by how easily you explained transformers. In both my Physics 2 and linear electric circuits courses the information I retained about transformers is v2/v1 = n2/n1 and v2/m = v1/L. Thanks for the refresher!
This video is really great. The use of physical modules and the analysis of each stage as we build the power supply out helps with understanding greatly. I know you already did the seitch mode power supply video which is also good, but i would love to see that video done again in this style. This way is so clear and tactile.
I’m not sure it can be done because of the parasitics of the connectors, and I don’t want to cover something twice. But I will definitely do this style for anything similar in the future!
Great video! Clever idea. Imagine building the schematic each time you add a block on top of video. People could have seen each symbol and see the entire circuit at the end.
Studying electrical engineering and power electronics are my passion. Unfortunately that focus is only offered in final year so I’m here to get my fix! Amazing video, never stop!
Dumb question.................on the schematic at 33:18, why does the ac circuit before secondary transformer not short circuit and burn up? If you take your ac plug in your house and connect a fuse and jumper wire between the ac side and neutral, it will immediately burn the fuse. Why not here? Thanks for the wonderful video!
Love this question! I spent years wandering this. It's because of the inductance, so even though the primary of the transformer has a resistance of only a few ohms, the inductance limits how fast the current can change so it can never reach excessive levels because the AC input means it is constantly increasing and decreasing. If you connected a DC supply at the same voltage the transformer would last probably less than a second! Hope that helps!
Excellent! I’m self taught in electronics and have been using voltage regulators for years with my Arduino work. Now I understand what makes it “tick”. Thanks a LOT!

Thank you for this incredible video! This is amazing yet so simple to understand! Now i know why i have components in power amp in such order and what is going on in that chain when it’s on. Incredible job to make people little bit more educated!
These videos and your teaching style are fantastic.
Great video, love those modular boards you made, really clearly explains how everything goes together! I'm a bit of a noob to electronics, I have used linear regulators before but haven't used open or closed loop ones, I will definitely read up more on it and experiment - thanks!
Great explanation and demonstration! ❤
I wish I had had access to content like this when I studied EE 20 years ago!
One of the best education videos you make. Every honor!
Very well done and easy to follow video, it will help many people
Thank you!
I absolutely love the fact that the power supply in this video is "linear", both in the electrical and physical sense! 😁
Fantastic explanation.
By far your best Video ive seen yet. All of them i learn something useful. Or it fills in a gap ive missed along the way from other channels.
Ive git a new FAV now.
YOU.
Beautifully done.
Years of interest in the field just to finally understand circuits are basically jumbled in a non linear compact cluster or they get put in a straight line to actually make arithmetic sense.
Where has this been my entire college education. This put half of my studies into one episode and actually made enough sense.
Impressive! Very very good mix of complexity and simplicity on the setting and the genious explanations! Wow
Ur such a good teacher..... im into electronics repair this days and u have cleared my doubts thoroughly on power supply ❤
I was pleasantly surprised by how easily you explained transformers. In both my Physics 2 and linear electric circuits courses the information I retained about transformers is v2/v1 = n2/n1 and v2/m = v1/L. Thanks for the refresher!
This video is really great. The use of physical modules and the analysis of each stage as we build the power supply out helps with understanding greatly. I know you already did the seitch mode power supply video which is also good, but i would love to see that video done again in this style. This way is so clear and tactile.
I’m not sure it can be done because of the parasitics of the connectors, and I don’t want to cover something twice. But I will definitely do this style for anything similar in the future!
New viewer. I've watched less than a minute... but I can tell you I'll be watching a lot of these!
Awesome!!!! I've been looking for a channel like yours for quite some time. You explain things so clearly and cleanly!!! :-)
Great video! I love the break down of the circuit, component by component, makes it very easy to understand, this deserves a sub :)
These explanation videos are absolutely amazing, thank you for sharing!
Great video! Clever idea. Imagine building the schematic each time you add a block on top of video. People could have seen each symbol and see the entire circuit at the end.
This is exactly the type of content I need to get back into electronics!
Awesome stuff. Really informative how you went over each component and bringing it into practice. Hope to see more of this!
This is such a high quality video!
Very informative and compact, explained everything without wasting time. Please keep making videos!
Studying electrical engineering and power electronics are my passion. Unfortunately that focus is only offered in final year so I’m here to get my fix! Amazing video, never stop!
Ahh love to hear it! And that is annoying, hopefully I can help and maybe you can do your own power electronics projects if you have time!
Dumb question.................on the schematic at 33:18, why does the ac circuit before secondary transformer not short circuit and burn up? If you take your ac plug in your house and connect a fuse and jumper wire between the ac side and neutral, it will immediately burn the fuse. Why not here? Thanks for the wonderful video!
Love this question! I spent years wandering this. It's because of the inductance, so even though the primary of the transformer has a resistance of only a few ohms, the inductance limits how fast the current can change so it can never reach excessive levels because the AC input means it is constantly increasing and decreasing. If you connected a DC supply at the same voltage the transformer would last probably less than a second! Hope that helps!
Great question
@@electrarc240thanks for clearing this up
Love your videos. Very informative and easy to learn. Thank you for explaining the importance of power supply isolation.
the best illustration ever. especially in the end with the circuit diagram.
Excellent! I’m self taught in electronics and have been using voltage regulators for years with my Arduino work. Now I understand what makes it “tick”. Thanks a LOT!
