A while back there were 24VDC 6A switching power supplies everywhere for $15. I bought more than I should have with the thought of turning them into a bench power supply with some real oomph behind them.
I've been doing some drafting with the thought of discussion. I may build it, I might not.
I had a minor epiphany in that a simple high speed dual op amp could be used as controllers if the voltage to the op amp power supply regulators were higher than the voltage they were controlling. So I came up with this circuit...
This is a simple high frequency inverter that uses a hand wound toroid that will extend the power supplies to the op amps about ±5V beyond the base 24V 6A power supply. The op amps would be powered by 34VDC.
This will allow this simple current regulator to work...
Followed by this voltage regulator...
I did not bother to show the pins or power supply pins on the op amps, it is assumed. I also did not show the meters I would use if I actually build this sucker.
What can I say, my idea of fun on a Friday night. Discuss (but not my idea of fun).
