摘要： An ignition control device includes an ignition coil, a main ignition circuit unit for performing a main ignition operation, and an energy input circuit unit for performing an energy input operation. A main ignition signal generation circuit generates a main ignition signal such that a point in time when a waiting time has passed from a detection start time of a first signal of an ignition control signal at which a signal level of the ignition control signal changed from a first level to a second level for the first time, and the signal level of the ignition control signal is the second level, is a start of the main ignition signal, and a detection end time of a second signal of the ignition control signal at which the signal level of the ignition control signal shifts to the first level thereafter is an end of the main ignition signal.

摘要： A semiconductor device includes a power semiconductor element that is connected between a first terminal on a high potential side and a second terminal on a low potential side and that is controlled to be on or off corresponding to a gate potential, a turn-off condition detector that detects whether a control signal input from a control terminal and controlling the power semiconductor element satisfies a predetermined turn-off condition, a first switching element that controls the gate potential of the power semiconductor element to be an off-potential when the turn-off condition detector detects that the turn-off condition is satisfied, and a detector for a collector current of the power semiconductor element. The turn-off condition detector uses the control signal and the collector current as the turn-off condition.

摘要： An ignition device includes: an ignition plug producing plasma discharge between a pair of discharge electrodes of an ignition plug; an ignition coil provided with a primary coil and a secondary coil, the secondary coil applying voltage between the pair of discharge electrodes; a voltage applying unit applying alternating current voltage to the primary coil, a frequency of the alternating current voltage being set to produce voltage resonance in a circuit including the ignition plug and the secondary coil. The voltage applying unit sets an output period of the alternating current voltage to be longer than a first period at which a partial breakdown start to occur at the pair of discharge electrodes, and shorter than a second period at which a total breakdown occurs at the pair of discharge electrodes, when an air/fuel ratio is lower than a predetermined threshold.

摘要： In aspects of the invention, there is provided an igniting semiconductor device that can prevent burning of an IGBT or ignition coil, and erroneous ignition, even when reducing the size of a capacitor that generates a self-interrupting circuit time constant. In some aspects, a semiconductor device of the invention is configured of an IGBT and a current control circuit. The current control circuit can be configured of a first series circuit wherein an IGBT and a sense resistor are connected in series, a drive signal control circuit, and a self-interrupting circuit. At a time of abnormal operation, the self-interrupting circuit can output a voltage whose amplitude temporally drops in stages toward 0V to the drive signal control circuit. The drive signal control circuit can control the amplitude of a drive control signal so that the voltage across the sense resistor is equivalent to the output voltage of the self-interrupting circuit.

摘要： A plasma ignition system has an electromagnetic noise reduction circuit in addition to a discharge power circuit, a plasma generating power circuit, a plasma ignition plug, a discharging wire and a plasma generating wire. The noise reduction circuit includes a first rectifier connected to the discharging wire, a second rectifier connected to the plasma generating wire, and a noise reducing capacitor connected in parallel to the second rectifier. The noise reduction circuit is disposed close to the ignition plug so that the noise reducing capacitor bypasses only high frequency noise currents generated when the ignition plug discharges.
