Ignition Coil Drive Circuit

[David C. Carlson]

I have observed that ignitions with transistor or mosfet drivers for the
coil do not have a capacitor (condenser) in shunt with the driver like
the old-fashioned points, condenser and coil system. I realize that the
switching times would be slowed by the addition of the capacitor.  I
always thought the L-C resonance increased the spark energy and
duration. Is the coil current collapse sufficient for spark generation?

I am looking for comments.
