sir tl494 use karke ek adjustable current supply banane ka tutorial denge bole the aap ???when will you be able to make that tutorial ?? i will be very grateful to you for that tutorial!!!

@HaseebElectronics Жыл бұрын

yes brother i am sorry for that delay. i promised, for that and i tried to adjust and i was able to adjust voltage, but i failed to obtain load regulation, so that is the reason, i skipped that video, because i don't want to share any incomplete or misleading information. as we can adjust voltage but underload, the voltage loose regulation and power supply produces ripples. but i will share a perfect and cheap solution to make a variable power supply using computer power supply

Thanks a lot for your valuable comment yes dear, if we understand the circuit, then we can operate it and repair it logically, it brings fruitful results otherwise it is like "a blindman sweeping in dark night"

Looks like a RAIDMAX power supply. I am working on one now, slightly different 400watt, uses a KA3843 for the PWM and an LP7510 for the Power Good , power on. Thanks for making this video. Everyone around the world thanks you I am sure.

@HaseebElectronics Жыл бұрын

thanks a lot for our valuable comment raidmax models use PFC to main dc line voltage and 3843 for secondary power supply while 7510 is atx supervisor

एक दूसरी पावर सप्लाई है उसमें सिर्फ फोल्ड यह है कि 3.3 वोल्ट धीरे-धीरे कम हो जाते हैं और सप्लाई ऑफ हो जाती है लेकिन जब किसी सप्लाई पर थोड़ा लोड किया जाता है तो सप्लाई को चालू रहती है रहती है 3.3 पर लोड करने पर ऑफ हो जाती

is mein 3.3 volt regulator ka problem he. kisi waqt 3.3 volt ka regulator transistor (jo atx supervisor ic k pass lagaa hota he) us mein problem hoti he. agr 3.3 volt mosfet se regulator ho rahey ho to mosfet aur us k gate per lagaa hua TL431 check kr lein aur terminal regulation wali ordange color ka connection check kr lein

please check the RCD snubber circuit (resistor, capacitor and diode) connected across the primary winding of the transformer i think, it have some problem please check the link kzfaq.info/get/bejne/q9ehbKehp93UpY0.html and please let me know the results

@@HaseebElectronics *Thank you my friend, on primary I get AC voltage all the way upto the transformer primary side, but then on the secondary side no power or very little power , so primary side AC power OK even large capacitor charge to 340v, problem is no power after the transformer secondary side, I have replaced all Bad components and IC have checked others out of circuit and are OK but still I can't get power to the secondary side*
