ABSTRACT:
A signal generator for use in a breakerless ignition system for an internal combustion engine, comprising a magnet rotor rotatable in synchronism with said internal combustion engine and a stator including a plurality of signal coils and a comb-like magnetic core member disposed adjacent to said rotor and having a plurality of teeth-like core portions around which said signal coils are wound, respectively, and a common yoke magnetically connected to said core portions, said signal coils constructed so that incremental voltages are established thereacross from the most advanced position toward the most retarded position and said signal coils divided into at least two series connections of at least alternate signal coils. Each series connection of signal coils has a diode connected in series to the corresponding series connection and the series connections of signal coils are arranged in a parallel manner. The signal generator is arranged so that one of the ends of the output is connected to a gate of a controlled semiconductor switching device in the breakerless ignition system and the other end of the output is connected to a cathode of the semiconductor switching device.
