AC-DC 30V Variable Power Supply

30v Power Supply:
-------------------------
- Transformer -> Bridge Rectifier ->
2-stage Filter -> Shunt Regulator -> Voltage Divider (Variable, tapped Potentiometer)

Both voltage and current can be controlled in this power supply.

If you want to increase or decrease the maximum voltage output, you can do so by modifying the transformer turn ratio and the regulator, filter capacitor and filter resistor values. This would also modifiy the current output (Amps).

If you have any suggestions on possible improvements or anything else, please comment.

Change the capacitor to about 5m farads, that will make it so the voltage drop is less than .1 volt, not 30 volts like it is now

Thanks for the suggestion, I did what you said and now it works really well.
