in this theory and practical tutorial i explained practical functional description to Understand & Repair Switch Mode Power Supply SMPS Practical troubleshooting. it is using FSDH321 current mode SMPS PWM controller. DH321 & DL321 are similar ICs but the main difference is switching frequency. Pinout is same. i demonstrated 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
