Abstract: This application discloses a high-energy ignition coil, wherein a primary coil and a secondary coil are both wound around an iron core, these three constituting a transformer. The primary coil loop is provided with a switch controlled by an ECU. The spark plug is connected at one electrode to an end of the secondary coil, and is grounded at the other electrode. An on-board power supply supplies power to the primary coil via a DC booster, which boosts the DC voltage outputted by the on-board power supply before outputting. The other end of the secondary coil is either connected to the DC booster or grounded via a reversely connected diode. A current keeping device is connected in parallel with a serial branch of the secondary coil and the spark plug, working after the spark plug is turned on to keep the spark plug on. The ignition coil of this application can regulate the on-time of the spark plug arbitrarily, and can thus increase the ignition energy; besides, in the ignition coil of this application a higher voltage is used to turn on the primary coil, thus improving the energy conversion efficiency.

Abstract: When a normal operation is detected by a self-interruption signal source and a first transistor is on, if an on-signal is inputted to an IN terminal, a second transistor is turned on and a third transistor is turned off. Accordingly, an IGBT is turned on. In this state, if an abnormality is detected by the self-interruption signal source, the second transistor is turned off and the third transistor is turned on. Accordingly, a gate terminal of the IGBT is connected to an emitter terminal via the first and third transistors, and charges accumulated by gate capacitance of the IGBT are rapidly discharged. Consequently, if a comparator detects that a collector voltage of the IGBT has exceeded a predetermined voltage, the first transistor is turned off, and gradual interruption in which the charges accumulated by the gate capacitance are gradually released by a resistor is performed.
