hello
to diode output i add a Snubber (c and r )
c=23nF,R=50ohm
when i turn off and turn on the adapter is unstable
the voltage all the time is up and down
if i remove the capacitor on the system become stable
the schematic is attached(if needs more details i add)
the transformer 1600uH 1:10,
vin 220, vout 12 (up to 500mA)
note :this is NOT the primary Snubber (for mosfet transistor),
