The Modular Bench Power Supply ++, testing it all on the bench with the BreadBoard

Robert Peter Oakes

Back to the Main post The Modular Bench Power Supply ++, The Essential DIY Build for Every EE Student and Old Timer alike...

 

Ok, so based on the last two or three videos an posts it is time to test everything out on the bench with a breadboard and read power to see how it performs

 

so this is the final schematic I have, I still am pondering changing it up a bit more but I will play with it a little first, ideas I have are around using 10V control signals instead of 5V and of course adding a pre-regulator switching in order to reduce heat dissipation in the regulator significantly, but thats for a future epesode image

RPO: The Schematic was updated to reflect the correct volts on the op amps of +12 and -12

 

and of course the video to explain it all

  • Hi Peter,

     

    I also left this msg on your blog.

    There is a small error on the diagram.

    The +12V is labeled +2V.

    You may want to clean-up the connections to the feedback resistor of the voltage comparator.

    Your schematic capturing probably messed that up.

     

    Looking forward to the next episode, I'm glued to the Tube.
