in this video i explained how is the feedback loop works in switch mode power supply. in smps the output ripples from the output of the rectifier are taken to to the optocoupler and the tl431 provides a offset voltage level to the optocoupler when the reference is maintained by the voltage divider network gets the regulated output level from the output filter capacitor. these ripples are transferred to the feedback pin of the smps pwm pulse width modulator ic, which adjust its output duty cycle to adjust the output voltage of the smps after watching this video you will be able to:- how to #design #build #make #smps how to understand smps, function of switch mode power supply, in this tutorial i draw the circuit diagram and placed components and made wiring of the components. 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 how to design buck boost converter how to draw zero volt switching ZVS zero current switching ZCS or flyback converter #smps, #repair, #troubleshooting, SMPS practical tutorial    • How SMPS Works || Understanding SMPS Switc...   SMPS tutorial and practical troubleshooting and fault finding    • {223} How to Design SMPS Switch Mode Power...      • Видео      • #207 SMPS Output Fluctuating / Low or No r...   LED LCD TV power supply circuit    • #219 LG LH T6240 SMPS Switch Mode Power Su...   17PW26-4    • Видео      • Видео      • Видео      • #183 How to repair switch mode power suppl...   Repair ATX Computer Power Supply    • #209 Repair Computer Power Supply /ATX Sta...      • #199 How to increase Output Voltage in ATX...      • #197 How to bypass Over Voltage Protection...      • Видео      • #189 How to repair Computer Power Supply /...   Adjust Output of SMPS    • #206 How to increase / Adjust Output Volta...      • Видео      • #206 How to increase / Adjust Output Volta...   Computer ATX power supply circuit explanation    • Видео      • #168 ATX POWER SUPPLY CIRCUIT DESCRIPTION ...   Youtube    / @haseebelectronics   https://www.dailymotion.com/haseebelect/ facebook   / haseebelect   Twitter   / haseebelect     / haseebelect   Types of Electrical and Eletronics Ccts    • Видео   Test Diode With Multimeter    • Видео   Check Resistance    • Видео   Check Resistance    • Видео      • Voltage divider circuit Practical   how to design switch mode power supply,how to design,smps,switch mode power supply tutorial,basics of switching mode power supply,smps tutorial,how to repair,basic working of switching mode power supply,smps basics,how to repair smps,how smps work,how switching mode power supply works,haseeb electronics,how to build,switch mode power supply,troubleshooting IF YOU FOUND THE VIDEO GOOD SUBSCRIBE COMMENT LIKE SHARE
