摘要： A voltage regulator circuit for an AC generator of an automobile is disclosed. The circuit comprises, in addition to the conventional elements, a transistor turned on and off in phase with the power transistor by the control transistor of the voltage detecting circuit. The collector of this additional transistor is coupled to the positive terminal of the battery through a resistor, while the emitter thereof is grounded. A serial circuit of a resistor and a capacitor forming a positive feedback circuit is coupled across the collector of this additional transistor and the base of the control transistor, a biasing resistor being coupled across the base and emitter of the control transistor. Thus, when the control transistor is turned on, the charging current of the capacitor produces a forward bias across the base and emitter of the control transistor; when the control transistor is turned off, the discharging current of the capacitor produces a reverse bias thereacross. A Zener diode is coupled across the collector and emitter of the additional transistor to limit the voltage thereacross under a predetermined level. Thus, the capacitor in the feedback circuit is protected from voltage surges.
