Daddy.... why does TK's scope display look so much better than LMM's fancy LeCroy screens? I thought TK had anemic, geriatric, garage sale equipment. Oh well, never mind, can I have an icecream sandwich? Please?

Oh Daddy, havent you analised her enough yet ? You have. 

You proved her circuit works better than v!agr@ 

Now please give some rest to your tool(s)  or else your chips will fry with overload.

Ps: Even Mur@kamis (snake oil salesman), throat is choked now. Take some rest.

Ah, it had to be something like that. Well, my daddy was colorblind, so don't expect too much from me.


Meanwhile, back at the lab....

Here's what the Vbatt and Vcvr traces look like with the MarkE gate boost circuit engaged. Warp 10, Scotty! Look at that spike in Vbatt, going all the way off the screen at the top, over 200 volts above baseline. (The measurements at top right are correct, as far as I can tell.) And see the nicely shaped main current pulse, which will waste less heat in the mosfet.

That is a great demonstration of parasitic wiring inductance and capacitance.  The faster that the MOSFET switches, the more pronounced inductive distortion is in the current sense, visible as rising to a higher value that then declines exponentially during the on phase.  And Warp 10 is right for that turn-off.  With limited parasitic capacitance to dump charge into, the greatly sped-up turn-off of the MOSFET requires a much higher voltage.  With a fast enough driver one can easily exceed the Vds rating of the MOSFET, which is why a TVS from drain to source is a good idea.

Do you mean to tell me that for less than $20. I can have the kind of sophisticated kit needed to prove over unity for my very own?  And that I will also get a Popeil Vegematic(r)?  Where's my credit card?

Nice replication TK.

Could you try a flyback diode across the resistor to see if the Vbatt trace changes?

Thanks.
