Abstract

PURPOSE:To shorten the non-saturation time of a power transistor and prevent the fluctuation of ignition position due to the fluctuation in power voltage, by inhibiting the fluctuation in the input bias level under energiation of an ignition coil but performing the fluctuation under de-energization of the coil.
