Re: Inductive Kick Effects
The "newly discovered effect" has in fact been a part of
electrical thingys harking back to Faraday's induction coil
experiments. Time must be taken into account in the calculations
in case someone starts wondering what happens to 11J+ of stored
energy in the ballast core.
When the gap fires, transformer/ballast current should be
approaching zero as the cap is storing most of the circuit energy at
this time. When the gap fires, the amount of magnetic energy that
gets stored in the ballast/transformer leakage L is going to depend
on gap dwell (which is not all that long) according to current at the
end of dwell: Ipk = Vpk*t/L. Note that V is decreasing during dwell
as the transformer comes down off its peak. That "I" then gets
plugged into the energy equation. In fact the effect shouldn't be as
severe as it might at first appear if this is taken into account.
