Abstract
PURPOSE: To shorten the processing time of a digital operation processing circuit by taking in contents of a counter immediately before setting a control command to the counter, and correcting an ignition phase change signal on a basis of the value of contents and setting the corrected ignition phase to the counter.
CONSTITUTION: Ignition pulse control circuit 3 is constituted by digital counter 9, pulse generator circuit 10 which generates clock pulses of a fixed frequency, synchronizing signal generator circuit 11 which genrates square wave h and pulse r synchronizing with single-phase AC power source 5, inverter circuit 11, AND circuit 13, AND circuit 14, and flip flop 15. An ignition phase is set to counter 9; and at an ignition phase change time, the actual value of counter 9 is taken in to correct the difference between the ignition phase change signal and the taken-in counter value, and an ignition phase is set to counter 9 again.
