in this video i demonstrated How To Repair Switch Mode Power Supply SMPS When Low OutPut Voltage & Fluctuation. i discussed in urdu hindi language. 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:-
