{455} If Open Circuit In SMPS Secondary Side, What Will Happen?

in this video number {758} i explainedIf Open Circuit In SMPS Secondary Side, What Will Happen? What Will Happen? if there is output rectifier, secondary winding, filter, dry soldering or open tracks or disconnected wiring track, the vcc capacitor on smps controller ic's vcc pin will fluctuate, and bulk capacitor or main dc smoothing capacitor will fluctuate, but there will no output at output terminal. download L2269 SMPS circuit sample circuit diagram https://bit.ly/3FwVqou if we have open circuit in feedback network, in that condition the output will fluctuate in above and lower from the rated levels. there will fluctuation on vcc capacitor and bulk capacitor or smoothing capacitor if we have some component short circuit in secondary side, there will output in some hundred millivolt with fluctuation and vcc capacitor and smoothing capacitor or bulk capacitor will fluctuate 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. 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 #smps_output #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 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 supplies, 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 supplies, smps basics, how smps work, chowk azam, switching mode regulator, very easy repair of smps, smps output voltage fluctuation 00:12 L2269 smps circuit working explained 01:00 how feedback works in switch mode power supply 01:30 how SMPS controller ic fluctuates or restarts 02:35 how to power up a power supply circuit for testing 04:46 why vcc capacitor voltage is fluctuating 05:36 SMPS have no output voltage 07:06 reason smps output voltage fluctuation
