    Am currently having an issue working on a hybrid high frequency inverter showing error 09,after changing output mosfets,it change to 06,then I observe some zener diodes I changed off hand maybe I didn't get the real voltages,pls can u help me with real values of those zener diodes on the small output transformer...with codes zd3,7,8 .
    It's 5kva/48v.

  • @PiotrK2022
    @PiotrK2022 6 หลายเดือนก่อน

    @HaseebElectronics It's worth to also mention that it may be also a failure in the transformer winding... I'm fixing right now a Modecom ATX SMPS with both failed switching transistors,bruned fuse and desoldered one leg of subber resdistor. I fixed that problems, turned on PSU, and I notice that output voltages are very low, fo example 12V rails has 1 point sth Volt. I also noticed that snubber resitor gets very hot and after some period of time, transystors failed once again and "blew" a fuse once again...
    After that failure, I inspected PSU closer and more precisely and I noticed that transfomer has sheinked nad wavy isolation. and looking from the top I also noticed that isolation layersare melted, so I removed transformer, disassembled it, what wasn't easy, because isolation tape was so badly overheated that it falls apart, so I had to scrape it peace by peace and I noticed that one of the wires in the center-tap tail is blackend partially, burned!!!!
    I have 2nd PSU based on the same chassis, but with increased output power, so I borowed transformer and transistors from it, put my patient back together and bam, it worked!!!!
    Transformer failed, but I have to admit that anyways it done the job perfectly, becuse isolution worked and didn't allow the sec. winding short itself with primary!!

      best regards and special thanks
      yes optocoupler is used for switching. just set its ESR value high to drive the optocoupler in saturation
      try to use TLP250, TLP350, HCPL3150 CY17 type optocouplers that is specially for isolating switching optocouplers
      of use any IGBT / MOSFET driving optocouplers

And according to instruction written on smps 17 volt is normal output voltage. How is that possible? Same pin maintaining two different voltage level!

    when i disconnect the smps from the motherboard i get the 5 volt .
    when i reconnected to the motherboard again no power on and capacitor baby and main are varying
