More recently I have started watching RUclips videos on different topics such as electronics, micro controllers, Arduino, Raspberry, UPS, Flash ICs and just to study I purchased a used Tektronix 100Mhz oscilloscope, RT809F Universal Programmer with basic adapters, Clamp Meter and so many other related stuff. Because I am a 60 years old retired person. I've enjoyed rediscovering building microprocessor-based projects, and particularly enjoy working with chips. Really one thing shocked me that there are so many our Pakistanis uploading videos and sharing their knowledge with others. I am amazed surprisingly the comment are coming from all over the world. Our government should not impose tax on RUclips viewers. Mr. Haseeb , I too would like to thank you for sharing your projects online. The few project videos I've seen so far are simple and easy to understand and your solutions are remarkably innovative, intuitive, and insightful. I am very grateful for your videos site and the projects and information you have uploaded. Just wanted to thank you and encourage you to continue this effort....Hats off to a job well done and keep up the excellent videos.

Maestro primero que nada gracias por compartir su conocimiento, he aprendido mucho de sus clases. Tengo un problema al aplicar este método, he deshabilitado la protección correctamente, pero cuando intento variar el voltaje con el potenciómetro se me quema uno de los transistores switching quisiera saber la razón y como solucionarlo, gracias de antemano. Saludos.
Otro problema que intento solucionar es que en ciertos rangos de voltaje se puede oír ruido saliendo de la fuente y no encuentro la manera de probar si es el transformador, me recomendaría aplicar barniz? @Haseeb Electronics
Please make a video on smps power supply circuit based on tl 494 ic and show how the feedback is working the working of signal transformer and in a nutshell explain the power supply working
This PSU ATX is using only one chip, if we have 2 : the supervisor and the PWM, where to put the potentiometer to double the value ? also, can we just remove the capacitors of the 5v & 3.3v if we do not plan to use them ? thanks !
Sorry to ask, teacher. If only after the PIN 16 SDC2921 IC was cut, then we didn't give Potentio as adjustable. How many Volts can the output voltage be??? Thank you for your answer...
Since all 3 rails are couupled, I think I'll make (when I find time), only 12V to 25v, since 5v and 3.3v will be proportional to 12v/25v rail, but I only need one rail of enough current. Challenge is to get it to work from very low voltage, near 0V to 25V. I think the best way to go would be to make one small separate pcb for my new control block.
taking enough constant current with wide range control of the voltage, it is near to impossible. it is best to disable all not-required output modify the transformer using turn/volt method so that the power supply will work in safe duty cycle. at the output , use an external linear voltage and current regulator i think practically it will good solution
Brother solution! I followed the tutorial in this video exactly, but when I tried to test it using a 12Volt lamp load, both the amperage and the voltage dropped, it didn't work to lift the 12volt lamp load!!! I have replaced the capacitor with the out resistor. but I haven't used the pot. just use a 47kΩ resistor on pin 1 of the SDC2921 IC and the voltage becomes 14.7 volts
Why in some SMPS the main cappacitor is one for 400-500V and in the others are 2 cappacitor in series for 200-250V? It's depend from the topology, or simply lower cost for lower voltage the cappacitors?
it depends on the topology if some power supply is design ed to provide high power output with regulation by means of PWM controller IC then most common topologies are used half bridge, push pull, full bridge. in this case it will need bidirectional DC current in primary, so it will use 2 capacitors if some power supply is designed with PFC facility to maintain DC rail's voltage, then the PWM controller is just for switching, and the line regualtion is done y PFC circuit. in this case flyback topology is used, so it needs 1 capacitor to provide unipolar dc current

Can we do a 1.2 volt to 24 volt variable?

@@HaseebElectronics Thanks for the answer. I must rethinking all of this bcos it's hard to understand for me.
In this condition we'll not be able to draw power as much as the capacity of this psu, as the controller having a stimulated feedback. Am I right?
yes you are right. the rated output will decrease automatically
👍👍👍👍
Dengan menggabungkan output 12v, 5v dan 3,3v apakah nilainya menjadu bertambah?
Mere liye toh car bhej hi dijiye roj bina car aane mein achha nahi lagta aur aaye bina rah nahi sakti. 😂😂Stay safe my sweet brother
Can use the potentiometer without disabling the voltage protection
no. if the protection is present, it will interrupt immidiately
protection must be disabled
can we make a supply ac 220 to dc 12 volt 60 amp without transfarmer
