Filed: 1980-10-09
Abstract: PURPOSE: To prevent ignition coils etc. from being damaged by heat by allowing the current in the ignition coil to be cut-off without generating sparks, if the current flows for a certain time in the ignition coil.  
     CONSTITUTION: An output Tr 5 continues on-state according to the output state of an ON/OFF duty control circuit 3. When this state continues for a prescribed time or more, a timer 9 detects said continued state, and a current feeding means 10 feeds the current I 0  which increases with time, to a resistor 8. While, a constant current controlling circuit 7 operates with the synthetic current consisting of the current I 0  and the current I 1  of an ignition coil 4, and when the current I 0  increases, the coil current I 1  decreases corresponding to said portion of increase, and the coil current I 1  can be reduced to zero. Therefore, the coil current I 1  can be cut-off without generating sparks on the secondary side of the coil 4 by properly selecting the gradient of the current I 0  which varies with time.
