Abstract

PURPOSE:To provide on the input part of No.2 semi-conductor switching element a circuit for maintaining in an operating condition No.2 switching element upon receipt of generating coil output generated during the non-operation of No.1 semi- conductor switching element so that stabilized high voltage for ingnition may be obtained. CONSTITUTION:If an alternating field is interlinked on an iron core 3 of ignition/ generating coil 2 by the drive of magnet dynamo 1, posltive and negative pole output currents ''a'' are generated in coil 2. Then if positive pole A output current is generated in coil 2, transistor Tr 6 is turned on and a shortcircuit current runs into coil 2 through transistor Tr 6. If signal voltage ''b'' is generated in signal coil 10 at the time of ignition in the neighborhood of a maximum value reached by positive pole A output current generated in coil 2, transistor Tr 8 is turned on and transistor Tr 6 is quickly turned off. Consequently, a primary high voltage is generated on the both ends of coil 2, resulting in the induction of high voltage for ignition in secondary coil 4 and subsequent generation of ignition spark on ignition plug 5.
