I used ATX supply for electronic converter to generate higher voltage.
Eventually I patched the converter, and reached a limit, the diode + MOSFET both latched.
I was able to put the converter back to working condition, however, the ATX supply also no longer works.
It still emits this typical clicking noise after switching it off, so I guess the high voltage side is still intact (controller IC).
I measured the diodes on the secondary side, there are two double TO220 diodes, both measure short (0 OHms), and two double diode (round case), which measure 180mV forward voltage.
Would you say it is worth unscrewing the PCB, remove the cooler grid + diodes, and install new ones?
I am not very experienced with these circuits, but have some experience.
This also is not about the high-voltage side of the circuit.
I can show a picture if this helps.
I picked up this supply a year ago from junk, never used it until recently for the voltage converter. Isn't very powerful at the 12V side, all it can crank out is about 3.6 Amps (routed through the dc/dc converter).
So, before putting in 5 hours of labour I should rather invest in a new one, or electronic transformer?
I would take it apart anyway in this case to get hands on the components, and because these circuits are interesting for me. If I can repair it with little effort, good.
