Hi Sven,
"I like the Sot227 design because they have an insulated housing and they can safely screw on a heat sink."
Just keep attention to less thermal conductivity when insulated from the heat sink.
"Can I charge a coil in the same way and then switch the stored energy over a spark gap?!?"
Yes except everything in a coil behaves opposite to a capacitor. As the energy in a coil is stored as a magnetic field (current) the energy is released when opening the circuit. In a capacitor the energy is released when the circuit is closed. Coils store the energy in the most common types of switched mode power supplies. The Ćuk converter use capacitors to store the energy. When opening the circuit of a current carrying coil the voltage increases to keep the current at the same level as being stored. No discontinuity in the current is allowed which makes the voltage of the open impedance fit the stored current. Thus an increase in impedance of 100 times gives an increase in the voltage of the same 100 times to keep the current running. The period of the pulse is decreased by the same rate and thus the power is increased also by the same rate as the energy isn't changed.
"Something seems to happen that Hector writes so I would like to find out. Maybe you have to irritate the iron properly. laughing"
The energy level change when the permeability of the coil changes. This parametric change can be used to harvest energy from the ambient.

Hello Ole,
Due to the self-made push pull inverter, I hope to get better results in the Ferroresonanz generation than with 50Hz sine AC voltage.
I think my power semiconductors are then broken as the core of the transformer at that time you saturated the peaks and the resistance was too small and a high peak current flowed.
I would like to switch a choke in front of the center tap as with the Mazilli converter or Royer to limit the ampere under circumstances may flow.

Mosfets: IXFN44N100P I use.
Yes, with the 3 Watt Pulser is only the 10kw ringing occurs. With Teslas I load a capacitor which then discharges suddenly, it is already the right time and performance plays a role.
