摘要： A current limiter in an ignition apparatus for an internal combustion engine including a differential amplifier 20 is able to limit a primary winding current of an ignition coil to a prescribed limit value which is independent of a voltage as sensed by a current sensing resistor 11, thus providing a highly stable operating characteristic. The factor of current amplification of the differential amplifier can be increased without accompanying oscillations of the current limiter. The current sensing resistor senses a voltage corresponding to a current flowing from the primary winding of the ignition coil to a power transistor 4 which turns on and off the power supply to the ignition coil. A reference voltage source 12 generates a reference voltage for comparison with the voltage sensed by the current sensing resistor. A differential amplifier absorbs a part of a base current supplied from a storage battery to a base of the power transistor on the basis of a difference between the reference voltage and the voltage sensed by the current sensing resistor. A plurality of output transistors 25, 102 are coupled to form a Darlington circuit which is connected between the differential amplifier and the base of the power transistor. Another reference voltage source 12" may be provided for generating a second reference voltage, the second reference voltage source being connected between the current sensing resistor and the second input terminal of the differential amplifier for supplying thereto a total sum of the voltage sensed by the current sensing resistor and the second reference voltage.

摘要： The power transistor unit 2A for controlling the current supply to the primary side of the ignition coil 3 includes a light emitting diode 10 coupled to the output of the control unit 1, and a phototransistor 11 optically coupled to the light emitting diode 10. The light emitting diode 10 and the phototransistor 11 together constitute a optoisolator. Thus, the ignition coil 3 is electrically isolated from the control unit 1, and hence a filter circuit for suppressing noise from the ignition coil 3 can be dispensed with.

摘要： An ignition circuit IG converts a battery voltage into a high spark plug discharge voltage. A resistor R1 inserted into the power supply path L detects the current flowing through the ignition circuit by converting the current into a voltage, and a level shift circuit LS shifts the potential level at both terminals of the detection resistor. A level deviation detection circuit regulates the level of a deviation voltage developed across the detection resistor, which is caused when an electric current flows from the battery to the ignition circuit, and outputs the deviation voltage. A reference voltage generation portion sets a reference voltage to be compared with the deviation voltage by a comparator COM. A clamping circuit CL suppresses variations in the power supply voltage corresponding to the level deviation detection circuit and the comparator, and protects the level deviation detection circuit. Thus, the influence of a surge voltage exerted on the comparator embodied in a monolithic IC is greatly reduced. Moreover, the accuracy in detecting a load current at the time of engine ignition is enhanced.

摘要： An ignition apparatus for internal combustion engine includes an ignition power unit 1A having an ignition coil 13 and a power transistor 14 for supplying and shutting off a primary current i1 to the ignition coil; and a control circuit 2A for determining ignition timing of the internal combustion engine and a period for supply of the primary current in accordance with driving conditions D of the internal combustion engine so that it generates an ignition signal Ga in the form of a pulse to the power transistor. The primary current is supplied and shut off by the power transistor in accordance with the ignition signal to produce a high-tension secondary voltage V2 from the ignition coil. The control circuit includes an oscillation circuit 23 starting operation from a point when the ignition signal rises and operating for a predetermined period shorter than a pulse width of the ignition signal, the waveform of the ignition signal thereby being made to rise gradually. With this arrangement, there is obtained an ignition apparatus for internal combustion engine by which faulty operation can be prevented at a time when the ignition signal rises and the size and cost of the ignition apparatus can be reduced without using a high-tension diode.
