<p>PURPOSE:To improve the setting efficiency of generator output voltage by means of the modulation signal of the constant frequency reference triangle wave signal for a mean value of the field magnetic current as an operational signal of the field magnetic current. CONSTITUTION:A signal voltage V38 and a signal voltage Va1 with the same polarity component are obtained with addition of a mean value signal voltage V31 of the field magnetic current If outputted from a current detector 31 and the constant frequency reference triangle wave signal voltage V38 outputted from a triangle wave oscillator 38. And, a signal voltage Va2 is obtained by addition of the signal voltage Va1 and the signal voltage 31. The output signal voltage Va2 having output signal voltage V34 of a voltage adjustor 34 as a target value is added to a comparator 35 as the operational signal voltage of the field magnetic current 1f subject to follow-up control. And, the output signal of the comparator 35 gains chopping control of a chopper 25.</p> |
