In this experiment I try the low voltage switching to see if I can get the same response as with the high voltage and spark gap solution to study the behavior.
The purpose of the extra diode after the mosfet switch is to exclude the working of the protection diode inside the mosfet. This way I block reverse current flow which would otherwise flow through that protection diode inside the mosfet.
* The most important thing I noticed is that the closer the 2 coils in the high impedance side (the 2mH coils) the better the amplitude on the low induction side (150µH coil).
* Ringing frequency in the low induction side is depended on the switching frequency.
