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. <br />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:-<br />how to #repair #smps<br />fuse keeps blowing<br />how to repair switch mode power supply when short circuit at input<br />if SMPS is dead or no ouput<br />if SMPS have fluctuating output or output voltage unregulated <br />if smps have short circuit in output<br />how to eliminate short circuit<br />how to troubleshoot #PWM #SMPS #controller when there is no switching from #MOSFET<br />if SMPS have a whistle sound or excessive noise or excessive heat<br />how to repair mobile charger<br />how to repair computer power supply<br />how to repair laptop charger<br />how to repair inverter of solar system<br />how to repair #UPS #uninterruptible power supply <br /><br />#smps, #repair, #troubleshooting, <br />SMPS practical tutorial https://youtu.be/7je0v8AiBB4<br /><br />SMPS tutorial and practical troubleshooting and fault finding https://youtu.be/E_dQcKAqm38<br /><br />Youtube https://www.youtube.com/channel/UCamuZ8n1PwdZpzxV32b1l_w<br />https://www.dailymotion.com/haseebelect/<br />facebook https://web.facebook.com/haseebelect/<br />Twitter https://twitter.com/haseebelect<br />https://www.instagram.com/haseebelect/<br />Types of Electrical and Eletronics Ccts https://www.youtube.com/watch?v=roYf5a7V5-g<br />Test Diode With Multimeter https://www.youtube.com/watch?v=Q1AmJZkSzAM<br />Check Resistance https://www.youtube.com/watch?v=mF1W_MU6jvM<br />Check Resistance https://www.youtube.com/watch?v=prrD4cBSZKs<br />https://www.youtube.com/watch?v=8gseVSHUNM8 <br /><br />IF YOU FOUND THE VIDEO GOOD<br />SUBSCRIBE<br />COMMENT<br />LIKE<br />SHARE
