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

SMPS Output voltage Fluctuation / Switch Mode Power Supply Output Not Regulated. smps output fluctuation term is used when the output voltage of switch mode power supply are not being regulated properly. not regulated amplitude of the output in any smps is called fluctuation. i explained in urdu hindi language. 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 #smps_output #fluctuation 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
