Successful TPU-ECD replication !

Low Inductance = low 'BackEMF'.

If he was going for 'BackEMF' I would think all units would have weighed a great deal because of huge amounts of wire and heavy cores.

None appear to weight much at all.

low inductance and a choke will return tonnes when run fast....

from an aa battery you can draw 26 amps at .5 volts    with almost a dead short .... hummmmm

and impose the returning kick to the source for output    so you have 26 amps plus the imposed hv spikes lol   not 120v at many amp

no way it will work like that eh?

ist!

Wrong. It depends on the switching speed. The faster you switch the higher the voltage. It works with low inductance coils. You have to switch in nanoseconds.

Incredibly true!
If you have a 500mHz scope to see it AND the switching part you speak of is the OFF duration. Even with that acknowledgment, my best interpretation of the construction of the TPUs would mean we are looking at ps ranges not ns ranges to have any useable 'BEMF'.

'BEMF' is nothing more than the return action of a stretched spring being released. It returns what is put into it but so quickly most folks can't make use of it.
'BEMF' is one step back after a single step forward. I seriously doubt a TPU uses 'BEMF' for anything as there is no gain unless you move in one direction only. I suppose it is great for making sparks and loud noises
