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： In a control device of an a.c. generator for a vehicle which is designed in such a way that for a first time right after an engine having been started, an output of the a.c. generator is suppressed to a minimum value, and for a second time following the first time, the output of the a.c. generator is gradually increased from the minimum value up to a maximum value to stabilize the revolution of the engine, the invention is intended to shorten a period of time required to suppress the output of the generator at high temperatures to thereby prevent a reduction in the charging performance of a battery. At high temperatures, a time interval of a timer 402, to which the first period of time is set, and a discharging time constant of a capacitor 407, which defines the second period of time, are both shortened on the basis of an output a of a temperature sensor 410. At high temperatures, a detection threshold for a revolution detector 401, on the basis of which the start of the engine is detected, is set to a low level to shorten an initial excitation period of the generator.
