<P>PROBLEM TO BE SOLVED: To control DC equalization stably in the entire operating range by equalizing the series input voltage of each of serially multiplexed inverters. <P>SOLUTION: This inverter control device 10 controls a serially multiplexed inverter system 1, in which the DC sides of a plurality of inverters INV1, INV2 are connected in series to a DC power source 2. Based on the rotational speed of AC motors M1, M2, in the operation ranges of high or low motor rotational speed of AC motors M1, M2 connected to each inverter, motor torque of the AC motors connected to each inverter or reactive current that does not contribute to the motor torque of the AC motors connected to each inverter is respectively controlled so as to equalize the series input voltage of each inverter according to the DC input voltage Vdc1, Vdc2 of each inverter. <P>COPYRIGHT: (C)2004,JPO |
