{286} SMPS Output voltage Fluctuation / Switch Mode Power Supply Output Not Regulated

SMPS Output voltage Fluctuation / Switch Mode Power Supply Output Not Regulated. i explained in urdu / hindi language. smps output fluctuation term is used when the output voltage of switch mode power supply are not being regulated properly. irregulated amplitude of the output in any smps is called fluctuation it may be due to many reasons 1. main dc capacitor is internally open circuit 2. vcc capacitor of smps ic is open internally 3. vcc circuit / bias circuit / auxiliary circuit is open circuit 4. output circuit have some short circuit capacitor 5. feedback circuit is not working properly, it may be due to reference circuit, TL431 reference, or optocoupler or its related components #electronicscreators #smpsoutput #fulctuation SMPS Output voltage Fluctuation,Switch Mode Power Supply Output Not Regulated,how to repair smps,smps,how to repair switch mode power supply,haseeb electronics,output fluctuating,reasons for smps output voltage fluctuation,switch mode power supply output fluctuating,smps feedback circuit,why smps fluctuates,feedback in switching mode power supply,fluctuated or unregulated output,amps explained,smps repair,how switching power supply works,how smps works You Can also check these videos for fluctuation problem    • {444} SMPS OutPut Voltage Low and Fluctuat...      • {466} SMPS Output voltage Fluctuation How ...      • {512} Why SMPS Fluctuates / Reasons for SM...   ATX POwer Supply Circuit Diagram Explained    • {570} ATX Power Supply Circuit Diagram Exp...   300 Watt Half Bridge Power Supply Repair    • {592} 300 Watt SMPS Circuit Diagram Explai...   How To Repair SMPS    • {528} How To Repair SMPS || SMPS Repair St...   in this video i demonstrated How To Repair Switch Mode Power Supply SMPS When Low OutPut Voltage & Fluctuation. it is a KA7500 / TL494 based push pull topology power supply, in this power supply that output was 5 volt instead of 12 volt. the output was unregulated and fluctuating. i found both smoothing dc capacitors open circuit. i replaced the capacitors and the supply started working normally. i explained practical How to repair switch mode power supply SMPS very easy. i shared my easiest and perfect troubleshooting techniques practical troubleshooting. smps concept and troubleshooting repairing or understanding repair switching mode power supply basics and working principle. also i discussed smps basics. after watching this video you can capable to:- how to #repair #smps fuse keeps blowing how to repair switch mode power supply when short circuit at input 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    • How SMPS Works || Understanding SMPS Switc...   SMPS tutorial and practical troubleshooting and fault finding    • Video   SMPS Output voltage Fluctuation,Switch Mode Power Supply Output Not Regulated,how to repair smps,smps,how to repair switch mode power supply,haseeb electronics,output fluctuating,reasons for smps output voltage fluctuation,switch mode power supply output fluctuating,why smps fluctuates,fluctuated or unregulated output,how to repair switching mode power supply,smps output fluctuating,switching mode power supply tutorial,very easy repair of smps,smps no output voltage how to repair switching mode power supply, how to repair smps, how to repair switch mode power supply, basics of switching mode power supply, smps output fluctuating, how switching mode power supply works, why smps fluctuates, reasons for smps output voltage fluctuation, switching mode regulator, very easy repair of smps, switching mode power supply, basic working of switching mode power supply, how to repair switch mode power suppies, smps output voltage low, smps repair step by step, smps basics, fluctuated or unregulated output, smps feedback circuit, reasons for smps fluctuation, smps have low output voltage, smps no output voltage, laptop charger repair, how to find short circuit in smps, how to repair smps power supply, how to repair smps, how to repair switching mode power supply, smps tutorial, basics of switching mode power supply, how switching mode power supply works, how to repair switch mode power supply, smps, switching mode power supply tutorial, basic working of switching mode power supply, how to repair switch mode power suppies, smps basics, how smps work, chowk azam, switching mode regulator, very easy repair of smps, smps output voltage fluctuation
