。[Scope of claim for utility model registration] In a current compensation circuit that amplifies the deviation between a current setting signal and a current detection signal and outputs a current compensation signal to a current command calculation circuit, a diode is connected between the input and output terminals of an amplifier that amplifies the deviation. A current compensation circuit for an inverter, characterized in that a limiter circuit connected in anti-series is connected to limit an increase in current during a transient period.
