회전 자계를 발생하기 위해 엔진의 회전에 의해 회전되는 계전권선; 전류를 발생하고 정류기를 경유하여 밧데리를 충전하기 위해 회전 자계에 응답하는 전기자권선; 밧데리 전압 또는 정류기의 전압과 소정의 값을 비교하기 위한 비교수단; 비교수단의 출력에 근거해 계전권선에 공급되도록 계전전류를 제어하기 위한 전류 제어수단; 밧데리 전압 또는 정류기 전압의 변화값을 검출하기 위한 전압 변화값 검출수단; 전압 변화값 검출수단의 출력에 근거해 상기 계전권선에 공급되는 계전전류의 증가를 억제하기 위한 부하응답 제어수단으로 구성되는 차량용 충전 발전기. A charging generator for a vehicle including a field winding rotated by the rotation of an engine so as to generate a rotating magnetic field; an armature winding responsive to the rotating magnetic field to generate a current and charge a battery via a rectifier; a comparison circuit for comparing a voltage of the battery or a voltage of the rectifier with a predetermined value; a current control circuit for controlling a field current to be supplied to the field winding on the basis of output of the comparison circuit; a voltage change value detection circuit for detecting a change value in the battery voltage or the rectifier voltage; and a load response control circuit for suppressing a rise in the field current to be supplied to the field winding on the basis of an output of the voltage change value detection circuit.
