Abstract

PURPOSE:To reduce a number of components, by charging a condenser by a non- saturation time at a constant current circuit by means of a circuit which converts a non-saturation time of a power transistor to a voltage and by using a circuit where a charge voltage of the condenser corresponding to the non-saturation time can be obtained. CONSTITUTION:A non-saturation time detecting circuit F detects a non-saturation time of a power transistor 200. A non-saturation time - voltage converting circuit G converts the non-saturation time to a voltage. The circuit G charge a condenser by the non-saturation time at a constant current circuit, and is a circuit which picks up a charge voltage of the condenser. A comparision voltage bias level change circuit H flactuates a bias level ing circuit I amplifies an output of the comparision circuit A, and controls a current flowing to the power transistor 200. An ignition coil 210 generates a high voltage in synchronization with the rotation of a pick up coil B.
