My first 37000uf PSU

[samsagaz]

Hi, i want to know if think that this PSU are OK.

and if some addon/improvment can be made. i will use the Fuses in the primary.

An externally hosted image should be here but it was not working when we last tested it.

I will use other DIodes not the MUR ones. i added these to use the footprint.


Thanks in advance

looks ok maybe a thermistor in primary to smoothen the inrush current.
And if you wan't to simulate your psu please put some internal resistance to your caps

You also need to include the resistance of the transformer.

Just for kicks, try putting a low value resistor (0.3 ohms, 20 or 30 watts) between C2 and C3, and another between C6 and C7. The resistor makes the downstream capacitors act as a low-pass filter, which removes a fair bit of diode grunge from the rails at the expense of a bit of voltage loss under load.

You can test this with Duncan's power supply simulator:
