simple bipolar power supply

[BodomChild]

Hi

how can I use this eschematic (or a simple one like this) to work with a sec. 24-0-24V, 5A transformer and give 30v (bipolar)?

I can't find a schematic to give 30-0-30. I hope someone can help me.

thks all

The schematic is the same whatever you do. All that is different is that for 30-0-30 volt output you need a 22.5-0-22.5 volt transformer, which you will be unlikely to find.

I'm sure a common 25-0-25 volt transformer yielding 33.5-0-33.5 volts will be fine.

thaks thanks thanks.

what a stupid question....but now I'm happy.lol

Better schematic:

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

well...you can also place 0.1uf in parallel with each diode of the bridge if you want...They reduce HF noise caused by the reverse recovery current being snapped off when the carriers in the diodes are depleted.
