摘要： A main IGBT conducts or blocks a primary current flowing through the ignition coil in response to an input ignition control signal to generate a high voltage on the secondary side of the ignition coil. The main IGBT and a current limiter circuit are integrated in a monolithic silicon substrate of an insulating gate bipolar power transistor. The main IGBT has a collector and agate connected through a depletion IGBT forming part of a constant current circuit, and a resistor. When a voltage generated across the resistor becomes equal to or higher than a zener voltage, a zener diode leads this current to an emitter of the main IGBT.

摘要： According to the invention, a primary winding of an ignition coil is coupled with an insulated-gate bipolar transistor (IGBT). The IGBT is controlled by a current restriction circuit, which includes a control transistor for performing the on-off operation of the IGBT such that the IGBT is made conductive upon occurrence of an ignition control signal, and nonconductive, when a primary current of the ignition coil reaches a certain value depending on a reference voltage determined by a bias circuit. The bias circuit has a condenser, which is charged by a base current of the control transistor to change the base potential of the transistor slowly, when the transistor is made nonconductive.
