PURPOSE:To facilitate supplying ignition pulses to all ignition arms by only one digital processor by a method wherein the respective arms and the counted values at which the corresponding arms are to be ignited at a specific control angle are arranged in a table and the ignition pulses are generated successively by using that table. CONSTITUTION:A counter 2 whose counted value is changed by one cycle during one cycle of an input voltage is prepared and set in such a manner that it starts down-counting or up-counting at the specific phase angle of the input voltage of a specific phase. The counted values of the counter 2 corresponding to the timings at which ignition arms are to be ignited at a specified control angle are arranged in a table corresponding to the respective arms and stored in a memory 7. At the time of operation, this table and actual counter values and control instruction angles are used to make a microprocessor 5 generate ignition pulses.
