Explanations:
–
–
tr rise time at given load resistor R and 70% of the output pulse height.
Lp primary inductance measured at 1kHz (secondary coile open).
Lstr stray inductance measured at the secondary side, short circuit at the primary side. If there are several secondary coils only one at the time is connected (measuring frequency 10kHz).
–
The ignition current is a set peak value where the voltage drop over the coil resistance is still insignificant (mostly below 1V).
