Abstract
An ignition control device includes a control unit to control first to third switching elements so that during ignition discharge, which is started by turning off the first switching element, energy stored on a capacitor is discharged by turning off the third switching element and turning on the second switching element for supplying a primary current to an end of a primary winding opposite to an end thereof connected to a direct-current power supply. During inductive discharge of a spark plug, the control unit non-intermittently turns on the second switching element so that the second switching element is turned on over a successive energy input time period, according to the operating conditions of an internal combustion engine.
