You should have changed the 4th bridge rectifier diode also. Since all other diodes and mosfet are short circuited and whatever caused that to happen such as a high voltage spike/high inrush current must have flown through the 4th diode also and must have barely survived from becoming short. There still a high chance that the diode will eventually fail when compared with the other 3 diodes

yes. i agree with you that is great suggestion.

@@shyamsuresh1723Naprostý souhlas je i dokázáno že i poslední dioda je poškozena, tento stav je velmi častý dochází k poškození PN přechodu a dioda v závěrném směru ztrácí odolnost proti průrazu. Proč to teď dioda vydržela je jednoduchá odpověď zdroj byl nezatížený a navíc byl připojen přes omezení proudu ( žárovka)

hi good time. how did yiu find out the type of zener diode in the mosfet gate drive and how did you choose a similar type of diode?
@HaseebElectronics4 ай бұрын
almost all gate drives are protected by a simple fast switching signal diode like 1N4148. so that the PWM controller ic will not be effected by negative transients generated by mosfet switching and gate discharging

Great job ! But how do you know the value of the dead zener diode ?

Poškozené jsou všechny čtyři diody je dobré je vyměnit všechny nebude dlouho trvat a tento zdroj bude opět na opravě nedávno jsem o této problematice natočil video na můj kanál. Dioda sice vypadá že je v pořádku ale její průrazné napětí se sníží až na třetinu. Při mém testu dioda která měla vydržet 1kV zvládla pouze 350V tudíž by netrvalo dlouho a došlo by k poškození i této diody. Multimetr nedokáže měřit takto vysokým napětím tak proto se nedá zjistit poškození v závěrném směru. Mám rád tvá videa hodně mě naučila pokračuj ve své práci a zkus změřit tu funkční diodu a prosím neber tento komentář špatně je to pouze rada. Děkuji

Assalamu alaik, please I have a question. How would you be able to find a replacement for the IC:s you find damaged? Do you keep a stock of them or how do you do that? I would like to konw. Old boards might help but I am not sure if that is the case.
@SanelKeysАй бұрын
Search on google for datasheet and/or replacement or equivalent IC.

Hi. Mr. Haseeb. I'm from Iran . I've a switching power supply that it's switching IC has been exploded. I would be glad if you can help me to find the number of this IC. Help me if you can . I've just two picture of it's board and i donot how should i send it to you . let me know the way. best regards m.sedighian.

@HaseebElectronics3 ай бұрын
if the smoothing capacitor is already charged or it is small in capacitance size, the lamp will not glow. actually the circuit draws current but that current is very low that, it cannot illuminate the lamp
