とするインバータにおけるＰＩ補正回路。[Claims for Utility Model Registration] PI is used in the control circuit of the inverter that drives the motor.
In the device equipped with an operational amplifier, there is provided a pattern signal generator whose output decreases as the frequency increases when the frequency of the inverter exceeds a predetermined value, and an output of the pattern signal generator as described above.
1. A PI correction circuit for an inverter, comprising a multiplier that multiplies the output of an I-operated amplifier and outputs the signal to a feedback circuit of the amplifier, thereby obtaining constant responsiveness regardless of the rotational speed of a motor.
