摘要： A vehicle generator controller comprises a voltage detection circuit for outputting a voltage detection signal D to regulate a generated voltage VG in accordance with a battery voltage VB, a gradual increase control circuit for outputting a gradual increase control signal E in response to the voltage detection signal D and a switching element for intermittently controlling a field voltage in response to the gradual increase control signal E, the gradual increase control circuit includes a smoothing circuit for smoothing the voltage detection signal D by a charging time constant and a discharging time constant and a comparator for outputting the gradual increase control signal E by comparing the smoothing signal with a triangle voltage, both the charging time constant and the discharging time constant of the smoothing circuit are set to one second or more and the gradual increase control signal E moves to a waveform for gradually decreasing the field voltage when the battery voltage increases. With this arrangement, the vehicle generator controller suppresses a torque shock when an electric load is turned on as well as suppresses the drop of a battery voltage when the electric load is repeatedly turned on.

摘要： The output current and drive torque characteristics of a vehicle generator during cold, startup periods are approximated to those of a warmed up generator by sensing the field winding current, and interrupting it for a time period prolonged by a feedback/charging capacitor (904) whenever it exceeds a reference level. The field winding current never exceeds the reference level when the generator is warmed up, whereupon the interrupting circuitry has no effect.
