{464} ATX power Supply with Active PFC HP 240- Working Explained & Repair / Troubleshooting

in this video i explained ATX power Supply with Active PFC HP DPS-240 - Working Explained & Repair / Troubleshooting . this computer PSU is 110v to 220v auto power supply. active power factor correction circuit is used to maintain 365 vdc even the input voltage are 110 or 220. it will boost the dc rail voltage so that the pwm controller IC will just have to regulate output voltage. How to repair computer ATX switch mode power supply SMPS very easy. this PSU is using uc3845 TL494 LM339 active PFC controller and also i discussed smps basics. after watching this video you can capable to:- understanding atx power supply basics circuit diagram schematic with complete tutorial in urdu hindi working of atx smps if computer power supply does not on, or fan runs and stops, fluctuation, turns on goes off again or fail to start short circuit, or fuse blows burns again and again how to repair smps how to repair computer power supply atx 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 ATX power circuit diagram / schematic explained    • #168 ATX POWER SUPPLY CIRCUIT DESCRIP...      • #178 ATX POWER SUPPLY CIRCUIT DESCRIP...   71 ATX Power Supply Circuit Description in Urdu / Hindi    • #171 ATX Power Supply Circuit Descrip...      • Video   how to increase output of SMPS    • #150 How to increase output of the SM...   short in put of SMPS and fuse burns again and again    • {145} Fuse Keeps Blowing in SMPS || S...   fluctuations in output of power supply    • #144 Fluctuations in output or Fluctu...   smps basics tutorial and testing    • Video   feedback in smps    • #142 FEEDBACK in Switch Mode Power Su...   how to repair troubleshoot smps    • Video   How to repair switch mode power supply SMPS practical troubleshooting    • How to repair switch mode power suppl...   SMPS / PWM basics circuit description with practical switch / switching mode power supply    • SMPS / PWM basics circuit description...   SMPS Switching switch Mode Power Supply repair Basics & Troubleshooting    • SMPS Switching switch Mode Power Supp...   SMPS practical tutorial    • SMPS Switching switch Mode Power Supp...      • Video   SMPS tutorial and practical troubleshooting and fault finding    • SMPS / PWM basics circuit description...
