in this video number {1002} SMPS output voltage fluctuating, unregulated output, i demonstrated how to test / troubleshoot and repair 12 volt 5 ampere 60 watt, KA3842, KA2842, KA1842, UC1842, UC2842, UC3842 UCC1842, UCC2842 or UCC3842 based flyback converter switch mode power supply, its output voltage were unregulated and fluctuating. i explained the possible reasons related to this fault condition.
SMPS OutPut Voltage Low and Fluctuating, SMPS Output Fluctuation. How To Repair Switch Mode Power Supply when the output voltage are less than the rated voltage and it is giving unregulated voltage, after replacing the faulty potentiometer in feedback network, the power supply started working normally.

Very very helpful to trouble shoot any smps. Thank you so much. God bless you. If possible pls make vedeo on output capacitor calcultion of smps high frequency like 20 to 50 kilohz .

Emeğinize sağlık efendim. Kondansatör beklerken bu potansiyometre çıkması ilginç bir arıza olmuş. Teşekkürler. Esselamun aleyküm ve rahmetullahi ve berekatuhu.

Great troubleshooting again, thank you. I was betting it was going to be TL431....and i was wrong. Many thanks, again.

Hi for 1 Amps load testing how much resistance u have connected and watts, PLZ share me the calculation also...

@HaseebElectronics 8 ай бұрын

it is 6.8 ohms 20 watt resistance (2 in series) total 13..6 ohms 20 watt P = V^2 /R (12*12)/13.6 = 10.5 watt I= v/R 12/13.6 = 0.882 Amper P = i^2*R 0.882^2 x 13.6 = 10.588 watts

Hello engineer: I have a switching power supply whose output voltages have increased, for example, the voltage of 3.3 has become 5 volts, 15 volts has become 25 volts, and 20 volts has become 35 volts; In your opinion, where is the problem and should it be checked?

@ramaswamyranganathan9171 8 ай бұрын

Sir I want to know why in SMPS I find that when voltage input is 230v it is giving maximum ampere but when the voltage is low like 100v or 110v it is not giving that rated current. Also it is universal type SMPS

I hate mains power supply because if failure the breaker switch trips and the fuse don’t blow i think company’s should add a small breaker in the unit to stop main house breaker from tripping
