- Thank you very much for clarifying this.

- Very similar to NSTs and OBITs which have a much larger secondary
inductance of course.

- Yes, indeed. Thank you.

- I am not so experienced in simulations as you are. Therefore I
would like to accept your generous offer to run the simulation with
my MOT data: no-load-output-voltage = 2232 Vrms, dc-resistance of
secondary winding = 70 Ohms, calculated secondary inductance = 30,4
H, all the other parts were copied from Piranha II.

- I first disconnected the diodes and all the other components. Only
the MOVs (2500 Vrms) were soldered to the secondary winding of the
MOT. They remained cold.
Then I connected the Piranha II circuit to the MOT and increased the
number of MOTs until the stayed cold. A string of 3675 Vrms was
necessary now. OK?
