{466} SMPS Output voltage Fluctuation How To Repair SMPS Switch Mode Power Supply Output fluctuating

in this smps repair tutorial i explained how to fix SMPS Output voltage fluctuation problem, How To Repair SMPS Switch Mode Power Supply Low OutPut Voltage, smps fluctuation fault have many causes. basically it happens when smps controller is unable to find feedback or some over voltage or short circuit protection is active, in this condition we have to search the root cause of the fault based on nature of fault CORRECTION. PLEASE NOTE THAT R6 IS NOT CONNECTED TO THE D6 CATHODE, IT IS CONNECTED TO C8 CAPACITOR. (IT WAS MISTAKE IN DIAGRAM BY ME, WHEN I WAS DRAWING THIS CIRCUIT). I AM SORRY FOR THE CONFUSING SHORT LINK ACROSS THE C8CAPACITOR Please check other videos on same fault smps output fluctuation    • {444} SMPS OutPut Voltage Low and Flu...   smps output fluctuation    • #144 Fluctuations in output or Fluctu...   it is a TOP214 based flyback converter power supply, in this power supply that output was varying 0 to 1 volt instead of 5 volt. the output was unregulated and fluctuating. top214 ic was unable to receive control voltage (feedback voltage). one zener diode was short circuit in secondry side, which was causing to drop all the output in secondary, so TL431 was unable to find feedback voltage and optocoupler was inoperative, that was the main reason that the optocoupler was not allowing to pass the vcc auxillary voltage to the control pin of the top214 smps controller ic. i explained the functional description of the circuit with circuit diagram & datasheet. so the troubleshooting becomes easy when we repair with schematic also i discussed smps basics. after watching this video you can capable to:- how to #repair #smps smps output fluctuation output is not stable or unregulated if SMPS is dead or no ouput if SMPS have fluctuating output or output voltage unregulated if smps have short circuit in output how to eliminate short circuit how to troubleshoot PWM SMPS controller when there is no switching from MOSFET if SMPS have a whistle sound or excessive noise or excessive heat how to repair mobile charger how to repair computer power supply how to repair laptop charger how to repair inverter of solar system how to repair UPS uninterruptible power supply smps, repair, troubleshooting, SMPS practical tutorial    • SMPS Switching switch Mode Power Supp...   SMPS tutorial and practical troubleshooting and fault finding    • SMPS / PWM basics circuit description...   Youtube    / @haseebelectronics   https://www.dailymotion.com/haseebelect/ facebook   / haseebelect   Twitter   / haseebelect     / haseebelect   Types of Electrical and Eletronics Ccts    • Видео   Test Diode With Multimeter    • 93 How to Test Diode, Understanding D...   Check Resistance    • Видео   Check Resistance    • Видео      • #40 Voltage divider Practical with re...   IF YOU FOUND THE VIDEO GOOD SUBSCRIBE COMMENT LIKE SHARE
