Control circuitry for an ignition coil

摘要

The circuit has a first semiconducting switch (T1) with a load path connected in series with a primary coil (L1) of the ignition coil and a control electrode (G) for driving according to a first drive signal. A second semiconducting switch (T2) has a load path connected in parallel to the primary coil and a control electrode (G) for driving by a second control signal.
