Abstract
PURPOSE:To reduce switching noise, by making feedback control so that the supply current from a switching power element has a slope waveform having a predetermined gradient with respect to time. CONSTITUTION:When the rotary speed of a generator rises to produce A.C. voltage across an armature winding 11, output from NOT gate 26 is brought to 0. When the battery voltage is higher than a predetermined level, output Q from D-type FF27 is brought to 0 and a slope generating circuit 30 decreases voltage Vout with a predetermined negative gradient. As Vout decreases, field current flowing through a power MOS.FET15 decreases. As the voltage of a battery 2 decreases, output Q from the D-type FF27 is inverted to 1, and the output Vout from the slope generating circuit 30 increases with a positive gradient. Consequently, the field current increases.
