DCP010505DB: Problems with the DCP01 series power module

user4637774

Part Number: DCP010505DB

Tool/software:

Power supply module DCP01 series，Will the change in the turns ratio of the primary and secondary coils caused by a partial inter-turn short circuit in the primary coil lead to an increase in the output voltage of the secondary coil?

No, a shorted interwinding turn on the primary will at best result in a decrease in the secondary winding volatge.

What impact does that have on the final output?

Output voltage could increase or decrease depending where the short occurs. Maybe check, how one sample compares to another and if a difference is observed then investigate how a shorted turn might have occurred (high voltage breakdown, moisture, wire varnish breakdown, etc).
