摘要： A voltage regulation system for automotive charging generator comprising an armature winding, a field winding for supplying magnetic fluxes to the armature winding, a diode rectifier for converting the AC output of the armature winding linearly, a power MOS FET switching element connected in series with the field winding for turning on and off the field current, a storage battery charged by the output of the diode rectifier, and a voltage detection circuit for detecting the voltage applied to the storage battery to turn on the power MOS FET switching element when the detected voltage is lower than a predetermined voltage and to turn off the switching element when the voltage applied to the storage battery is higher than the predetermined voltage. The voltage detection circuit includes a comparing circuit D-type flip-flop so as to compare the voltage of the storage battery with a reference voltage, and in accordance with the result of this comparision, generate a signal at the complementary output of the flip-flop for controlling the on and off of the power MOS FET switching element at a time point synchronous with the bottom of the AC output voltage.
