摘要： A voltage regulator circuit 3A for a vehicular AC generator 1 includes, in addition to the conventional voltage detector and transistors, a bypass PNP transistor 315 for supplying base current to the power transistor 305 upon disconnection of the line A from the battery 4. When the engine is started and the AC generator i is driven, a small voltage is induced in the armature coil 101 due to the residual magnetism in the core of the field coil 102 even when the line A is disconnected from the battery 4. A smoothed voltage developed at the junction point between a resistor 312 and a capacitor 313 coupled serially between a phase of the armature coil 101 and ground turns on the NPN transistor 311, thereby grounding the base of the PNP transistor 315 through a resistor 314. The PNP transistor 316 is thus turned on, and the base current of the power transistor 305 is supplied through the PNP transistor 315 via the bypass line B.

摘要： An output power control device for an automotive AC generator includes a field current limiter circuit 9 for controlling the duty factor of the power transistor 305 coupled in series with the field coil 102A of the AC generator 1A, which is supplied with a maximum field current twice the conventional level. A frequency-to-voltage converter 903 converts the input frequency to a voltage corresponding to the rpm of the AC generator 1A, and a comparator 909 compares the sawtooth waveform generated by a sawtooth waveform generator 908 with the output of the frequency-to-voltage converter 903, the upper level of which is limited under a predetermined level by resistors 904 through 906 and a diode 907. When the rpm of the AC generator 1A exceeds a predetermined frequency, the pulse train generated by the comparator 909 reduces the duty factor of the power transistor 305, thereby controlling the level of the output current generated by the AC generator 1A.

摘要： A voltage regulator 3 for controlling the output voltage of the AC generator 1 includes two voltage dividers having junction points J1 and J2 coupled to the zener diode 306 controlling the ON/OFF of the controlling transistor 309 and the power transistor 310. The voltage level at the junction point J1 is varied by means of the short-circuiting transistor 313 in response to the output of control transistor 401. Usually, the voltage at the junction point J1 is higher than the voltage at the junction point J2, and the output voltage of the AC generator 1 is controlled on the basis of the voltage at the junction point J1 to a normal and a reduced level in accordance with the output at the target voltage change-over terminal B. When quick charging is needed, however, the control transistor 402 is turned on to ground the junction point J1, such that the output voltage of the AC generator 1 is controlled to a higher level on the basis of the voltage at the junction point J2.
