Constant Current Regulator

[power_speed]

Hello all,
New to this forum, so I say howdy.

I am looking for a nice simple and easy design, for a current regulator.

I need it to output 14vdc at 20 amps.

The trick is I don't want it to shut down when the 20 amps is reached, I want it to continue providing the full 20 amps but no more. Also variable current under the max amperage is needed based on load.

Please Help a newbie.

Can anybody suggest a good op amp for my above mentioned purpose.

Here is the link to what might work.

a cheap 741 Op Amp is ideal this purpose.
