cause sometime I need to do experiment with 24V, however, sometime I need to do projects on 1.1V or lower. So I have an idea to make one 0-10A and 0-30V power supply. :lol:

isnt 10A too much for a do-it-yourself power supply. i dont say that its impossible but the design gets comples. anyway the following is a link to a 0-30V and 0.002-3 A power supply. u can also check the forum on that site for the discussion about this power supply
i think that this power supply will fulfill most of your needs. speaking about needs, will u plz tell me what type of work do u need to do with this power supply. maybe u dont need to reach the 10A mark
I have a schematic for a linear supply that will easily do what you want. Almost any voltage or current can be obtained, But it is a fairly complicated circuit.
You can E-mail me at:
For something this big I would definitelly go with switching instead of linear power supply. That would keep the heat down specially when dealing with low voltage output and high current.
For example if you were to use linear PSU to drive 5V 10Amp load,
the regulating transistors would have to dissipate ca 300W of heat.
