Michael J Nunnerly's STEAP TPU ideas

[RAMSET]

Michael is open sourcing some very interesting work.
a result of years long investigations .

snip
Some ideas that I will now open source which have dated
back to my “STEAP” work a long time ago.


Here are two schematics, the first is the original but with what I call an internal feed back via D2, I
have never shown this before due to lack of interest by others. The start voltage is 12vdc, but the
feed back voltage at the point between D1 and D2 can be around 100v, so some form of voltage
control is needed in case of runaway. C4 charges and maintains the run voltage, when tuned to the
correct frequency no current should be seen across the CSR.

Stupid thread

@ramset,

What's the point of this stupid thread?

[Allen Burgess]

Nerderly.

@ramset,

You're supposed to know about this? What's it all about?

[Allen Burgess]

New thread

@ramset,

Maybe you should start a new thread up?

[Allen Burgess]

testing

@ramset,

Where's your testing? We need to see something!

[Allen Burgess]

Sidetracking dialouge?

@ramset,

I will remove this post in 5 minutes if I'm side tracking any dialogue!

Respectfully,

@ramset,

Take a look at yourself:

Looks interesting!

Hi Ramset,
I am going to build one of these. Looks very useful. What does CSR mean in the pdf?

Sounds like there are some other gems from Mr Nunnerly? Pity about the other comments. that's forums for you!

Edit: have found the resistor CSR! Printed off the pdf and ink was low so not all type clear.

Hi Dwane,

Csr stands for current sensing resistor. It is there so you can measure the voltage drop across the resistor with a scope or meter to calculate the current going through the circuit.

Hi,
Thanks for the reply, I worked that out. Having printed the pdf file, the image was badly reproduced, and with my bad eyesight, I missed it on the circuit diagram. All good. This useful looking circuit is about number 4 on the cab rank!

Dwane
thanks for the interest, I will be catching up With Mike in the next few days
I believe there will be more to discuss then.

also I will start a new topic [these posts above are from a ruff time here
which has been resolved.

Respectfully

HI Chet,

Am also wanting to hear about this as parametric circuits are of interest to me too. Thanks for posting such info , will be waiting to hear more about this .
