Abstract
An inverter control device including at least first and second inverters includes: a current detector that detects a current flowing through a main circuit of the first inverter; a current controller that generates a voltage command value of the first inverter on the basis of a detected current and a current command; and a voltage command predictor that generates a voltage command value of the second inverter on the basis of a variation of the voltage command value of the first inverter.
