in this video i demonstrated How to increase or decrease output voltage by altering inverting and non-inverting inputs in ATX power supply using AT2005, AT2002 Voltage mode PWM SMPS controller Power Supply For Higher Output Voltage
i explained practical How to repair computer ATX switch mode power supply SMPS very easy. this PSU is using SDC2921 IC which is PWM and intelligent power supply monitor. i simulated the outputs of the power supply using a voltage divider network supplied with +5V SB local power supply. after watching this video you can capable to:-

28:40 Why not increase the frequency? Will that not prevent the cores from saturating? If not the frequency, what if I need 24V? Rewind transformer?

[@HaseebElectronics]

it will not increase frequency, it will adjust its duty cycle. i will explain in upcoming video to modify atx power supply

[@ASMRChiChi]

Perfect😍😍

[@TheJavaSync]

17:51 - when increasing Vout, why duty cycle decrease on the osciloscope?

[@HaseebElectronics]

This signal is inverted in next switching transistors to drive pulse transformer

Hello Mr Haseeb, as usual, very delightful video ! I tried to do the same and i wanted to know what to do with supervisor sensing pins that have 2 traces coming to them, when i cut them both, i cannot adjust the voltage from the TL431 resistor and i still have some voltage protection... should i cut ALL the traces going to the pins or just one ? for the adjustable voltage do we put the potentiometer at the PWM IC or supervisor IC ? thank you & Salam Aleikum

[@hichamtassi1753]

Haseeb Electronics the PWM IC is the 4 pin UC3843B and the supervisor IC is the TSM111CN. Pin for 3.3v sense is stable and do not change so i left it as is. I cut all the tracks going to Pin 2 & 3 maybe there is another pin to disable...thank you & salam aleikum

[@hichamtassi1753]

Salam Mr Haseeb, did you have time to check on the circuits i gave you to tell me how to disable the protection ? thank you & Salam Aleikum.

Hi sir milind for pune

[@abangx]

what about current adjustment? can it be modified?

[@HaseebElectronics]

AT2005 Pwm controller don't have current mode error amplifier. if we want to control current, in that condition we need and additional current regulator circuit in output

[@abangx]

@@HaseebElectronics but possible on TL494 chip PSU right?

[@HaseebElectronics]

@@abangx yes in tl494 it is doable easily

[@abangx]

@@HaseebElectronicsi was messing around with PSU with chip 2003, and burned the chip, then i managed to modified it using CD4047 simple SQUARE PWM injected to the pin 7 and pin 8, everything went well, adjustable voltage was succeed, but the bad side, no current power, meaning if i set to 5 volt and add load, the voltage dropped to zero what did i missed? the schematic is here danyk.cz/s_atx04a.png if you have time, please help me solve this
