Hi! I'm designing a power supply that can output 12v and 24v simultaneously at the same time using a 12 0 12 CT Transformer. Is there any good circuit for it?

Hi v,
Welcome to AAC
Yes its possible to get 12V and 24V, supplies from that transformer, what current and level of voltage regulation do you have in mind.?

Note that with a rectifier circuit only and a 12V transformer you will get more than 12V/24V output - something like 14V/28V. You could use regulators to back to 12V/24V and make the voltage more stable.

I made the circuit and I've tried the schottky as well as the rectifier diode and I got a whooping 34-35V from the 24V line which what I aiming to get. And about 15-17V on the 12V line.
The rectifier diode gives me less than my desired output voltage so I sticked to using 1N4007 diodes for the application.
