<p>A simple form of ignition driver and control circuit for the coil power switches of an inductive ignition system for setting and controlling the primary current Ipo in the coil primary windings (@ 3) of ignition coils (@ 2a, 2b) of a multi-cylinder engine with 'n' powerswitches S1 through Sn, the driver circuit being comprised of 'n' isolation diodes with only one common control switch, a comparator (@ 10) and a common input trigger circuit working in conjunction with a current sense circuit with partial temperature compensation and the comparator to set the power switch on-time duration, Tdw for sequentially energizing and de-energizing the ignition coils as dictated by an ignition spark firing and sequencing system.</p> |
