Oh ya I forgot. I put a circuit breaker right after the transformer.

Hey thanks. I need to explain something here. I'm not that learned. My view is this. Lower alternating current off of the secondary then goes to a full wave bridge rectifier since I want it isolated from the ground so it takes 4 diodes. Diodes only let current pass in one direction, the...

Thanks, will do.

Hey, that's a good circuit diagram, only it's missing the ripple inverter transistor.

Thank you for all the help. Making and posting a schematic for something this simple seems to much of a hassle to me as I only need to connect two leads of a transistor up. Thanks anyway. I think I'll just go and try to figure it out by myself.

Also, what do you think of Pyramid's line of power supplies.

I don't know how to post a diagram even if I had one.

Transformer 30v 20a, bridge rectifier standard, filter capacitors 20k each, power transistors 15a each on top of each other with heat sink, and potentiometer from the high side to the base.

Are you sure. Sounds like you would like to insert it on the high side power line. That sounds like putting a secondary control before the control. Is this right?

The control transistors are up and running. I need a ripple remover circuit after the capacitor filter to remove the ripple. The ripple remove has to invert and insert the ripple to the control which is variable on the power transistor's bases. A transistor with a zener would work if the power...

The specs are npn silicon the base comes on at .2v and they work good.

Max 30 amps? 15a each? 0-40 on the volts.

I'm setting up an analog power supply. I have the transformer bridge and filter capacitors so far. The transformer puts out 30 volts. I am currently using two parallel power transistors and a variable resistor to set the output. It also has a meter to monitor voltage. The question is this. How...
