Yes, that is correct, but instead of a TIP35C, I have a 163H72 NPN transistor which seems to be able to handle all the current that the transformer can deliver. I have split the power supply into pos and neg so they can be simmed because spice won't sim if both sides are present, I also had to remove half of the LM324 op amp which was use as a buffer because spice wouldn't sim with it in.EDIT: Your schematic has a TIP35 NPN connected to the LM337 instead of a TIP36 PNP.
This time your right, **broken link removed** , I scrolled down to the 7812 schematic to get the 100 ohm resistor.Sorry, I was wrong. The transistor in the high current negative supply should be NPN.
Your base resistor value is 100 ohms but datasheets show only 3 ohms.
I agree with you about testing, that's where Spice is great. As for using LM324, that's what I'm using for the positive side, on the negative side, I'm using a MC34071 ( best I can remember) because they must be able take 24 volts and my application don't need to be that responsive and should be plenty fast for my uses.Hi,
I would recommend careful testing of any power supplies found on the web no matter where they come from.
Also, i saw a power supply design using LM324 IC's for part of the control circuit for the feedback. Although these parts can work, they are a little slow for power supply designs. The better choice is the TL082 or similar op amps which have faster response. In fault modes we want the circuit to be able to respond as fast as possible.
