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 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!
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.
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! 😘
Very Good information Video thanks for making such excellent informative Video and helping all people's who are interested to modifie their power supply as per their requirement.
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.
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.
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.
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😀👏
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
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.

Hi, How to reducer amp of12v. 84 AH car Battery to 13 amp.dc to connect with UPS ( replacing UPS 7amp battery. ( when I connected its work for 6 hours next day not working cause two mosfets burn completely one partially out of four ) I use this only for PC. Will you help me with a solution. Thanks in advance.
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
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
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
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.
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
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.
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
你好，我需要设计一个DC-DC降压转换器，将250V至600V的直流电压降至90V以下，同时增加电流。我了解涉及的风险。 Hello, I need to design a DC-DC buck converter that can step down an input of 250V to 600V DC to a voltage below 90V, while increasing the current. I understand the risks involved.
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.
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
I am wonder.. why just simply don't modify output voltage divider??( it shut work flawlessly) one resistor(or use potenciometer instead) change + nescesary volotage capacitor?? i must be honest it is good DIY solution.. i am just curious.. keep up this work it is good :))
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.
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.
u cant. to increase current ,voltage need to be reduced. total power voltage x current remain same. other wise big transformer to be used lot of changes
@@momsad8268 Here the video explains to change voltage by maintaining same power. if u want to change power all transformer size and other input sid e components etc will reduce just like a new SMPS. What is ur actual requirement? u need to design new power supply it self ? or modify the existing one?

Can you do this with an IGBT welding inverter?
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

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
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.

Hi Baby which sound are you using to make videos??
tried. But my transformer has 2 coils winding in opposite directions and ennd at 2 different pins.
Most of time you have to change the ferrite Core with a bigger one and the power tranistor the as well.
yes for small powr applicaiton LM317 AND transisor is better see my vedio
Not if the VA (Volt Amperes) rating is kept at or below the original
