To disassemble a transformer/ferrite core: Just put it im boiling water for just a few seconds up to maybe half a minute.. Everything comes apart without having to use any force, and there is no part of the transformer that could take any damage from being submerged in boiling water. It's definitely the quickest and simplestway i have ever tried, and with the lowest possible risk of chipping/breaking the ferrite core.

You're one of my favorite KZreadrs. Keep up the good work

excellent, not just it gives how to control, it sheds the light on each n every minor thing in detail

You are awesome very clear, well spoken on each topic, not leaving a lot of loose ends in the form of information the viewer is left wondering how to figure out the piece of information that was left out and still quite frustrating to find elsewhere. So thank you thank you thank you!

Your, video on power supply I like most, and I had built many of them with success, thank you, love your videos, 👍👍👍👍

That's an impressive piece of engineering redesigning, little bit beyond me, I still prefer to go to this electronic surplus store and rummaged through the power supplies until I find one that meets my specifications. I don't want to take anything away from you, but I think if I tried this, it would probably end up in smoke. I like to hear from other people that tried it and see if they made out okay.

In a long search, finally in this video I understand it much better because iam asembling for the first time a dc to dc flyback converter. Tnx my frnd very helpful to my projects😀👏

Lady your freakin awesome. I doubt i can figure any of this out but i thought you should know your a bad ass. Thanks for the knowledge

you are genus . no one did what you do before . congratulation . go on . and good luck

Thanks for your support,I learn about it, but I don't have any to answer a lot of questions it's running in myself to understand sometimes basically! 😘

Excellent work.

Thank you, you're very knowledgeable, and your videos are great

Transformer is the key component. I had plenty of 24 volt power supplies and I wanted to make them 12 Volts. I tried many things and broke the transformer core. This video tells me that with soldering iron I can melt the glue. Thank you for that information.

Thank you for your usefull information about current .

Really interesting, dude!!! 😃

perfect / its real good experience i love it . thanks kasyan

This video is very useful to me , Thank You Very Much.

Very useful video. Excellent 👍

I love your videos there are very clear . I would love to see how to have constant current and voltage with seperate controls for a server smps possibly two units in series thank you again

Nice job!

Thank you so match for this information

Knowledge its always handy.. I Thank you for sharing!!!

Nice info, thanks for sharing, like it :)

you are genius > i never seen like this video before . i think its exclusive . i love it soooooooooooooooooo much

Thanks for tutorial

This is the first time I've watched a video of yours, and although 2-years has passed since its original launch: the information contained within is well and truly on par for my current needs. I don't mind admitting that I still have a ways to go for the completion of my project, but at least I'm one step closer. Thank you for a great job.

Would love if you could make a video on using a laptop charger of 18 volts 3.5 amps and modify it into a 5 volt 30-40 watt usb multi port charger. Its something everyone would love

Very intresting. Would you recommend me to use that method to just to increase current out put of my pc psu so i can have more wattage out of it? Would that work?? Thanks for the video very very informative.

No that will not work since you have to reduce the voltage to increase amps

Hi i have projector power supply for 5v 1amps, for micro controller standby supply used. In this unit LNK362 ic is used, but it has exploded . We try to fix it by replacing all components but still power supply is not working, my friends saying that transformer may be defective. Can u suggest to fix it. Any other Ac Dc 5v cannot fix already i have tried.only to fix it or replace new unit.

Simply just use one with higher currect capacity.Or calculate and make a new one using larger core,bobbin,wire diameter,different number of turns,recalculate overcurrent protection.Different output diodes and capacitors is the most easiest thing.

simple rule: if you need youtube to mod smps, esp. to increase output voltage - don't. Use step-up converter instead.

Do you have a video showing how to separate the 24v output from an old printer power supply to use the said output for other components that needs 24v power supply. Thank you.

I did mine,but faced a reoccurring problem,the driver ic and mosfet keeps getting blown after 2-3hrs of operations,what could be wrong....?

Can you do this with an IGBT welding inverter?

Awesome I subbed cos power supply is expensive and I have so many different voltages.

You can simply reduce the value of R14 resistor ....and if you want strong courant flyback is not good. Use push-pull designe only with transistos no need fo ic ...not stable voltage but higher courant and good efficiency

Kasyan i have a question i have a LED power supply 12v 33A however i want o change it to 2.5~3V 13~160A my purpose is to use it for Electrolysis VOLT is irrelevant for that except heating up the solution i dont get anything out of it! is there module for this? what is it called if not how can i make one to do this tnX in advance

great

I would like to know if that current increase is already on sale?

Lady, I want to change AT computer smps to variable voltage and current ( 40V , 7Amp ) to run 50 watt led @36v , 1amp , shall I send you the pcb pics of smps

What about current sense resistors. Can you just modify that to increase the current a small amount

4:10 more convenient huh? showoff lol. i probably would have destroyed that board doing that so quick. great video... I'm looking up the power supply throttle thing and I cant find much about it anywhere else.

Thanks in advance.

I had done this idea before but in reverse, I had increased the voltage but my current is too low and no idea how to increase it, can you suggest any idea, to increase amp with voltage,ic is VIP22A

Current depends on Secondary wire thickness depends and turns voltage on no. Of turns. I dont know about frequency becoz u need dc right. So dc has no frequency

please check transformer size

could build a ct sensor limiter for grid tie inverter .so the inverter wont back feed the grid

Yeah I'll just build my own. My current project needs to take 215 nominal amperage and buck it down to 200 regulated amps to feed a 200 amp panel for a fully DC house. No AC will be on the property, no transformers, no inverters, all DC. DC Heat, DC air conditioner, DC refrigerator, DC washer and dryer, DC TV, all these things exist and are on the market. 3 socket receptacles will be available throughout the property. 12v, 20v, (a small few of the wall plates will have USB A 3.0, while most others will be equipped with USB 4 PD [all USB 4 use type C socket]). No need to rectify as source and supply are DC, no need to invert as all appliances will use DC. That being said there will be two inverters. One for just in case, and one for an EE lab. But not to run the o-scope, it's also already DC. Why? To troll you duh. Nobody's building that house lol.

u need voltage doubler with many diode and capacitor.

you should teach not only what you do but how you do it ... for example how you determined the number of turns of the secondary of the transformer

@ivicajanco9921

Use the length of the unwraped wire. If originaly for 12V there is 12cm wire, you need 1cm per volt (for example ofcourse) . So you mark the wire and wrap back to the mark and if necessary wrap some more to the right output contact then cut the excess wire. It is better for a wire to be a bit longer and to adjust correct voltage by resistors then cut it to short.

You have a beautiful voice. Saying you prefer to build from scratch, implies that only virgins are desirable,, just a point of view really, but important in that taking anything for granted is a mistake.

Most of time you have to change the ferrite Core with a bigger one and the power tranistor the as well.
