<P>PROBLEM TO BE SOLVED: To provide a control device of a power converter capable of properly tuning the amplitude of a compensation voltage at dead time. <P>SOLUTION: The control device of a power converter includes: memory means which stores a compensation voltage for suppressing a voltage, that is supplied to a motor from the power converter, from being distorted at a dead time set on the power converter; and adjusting means which controls the power converter based on a total voltage command generated by adding the compensation voltage to a voltage command corresponding to an ideal current command, and adjusts a drive force by adjusting a value of drive current that flows into the motor from the power converter if there occurs excess or deficiency with the drive force of the motor based on the total voltage command. The control device further includes correcting means which corrects an amplitude of the compensation voltage so that a difference in value between a current pulsation value that occurs on the drive current when the value of the drive current is adjusted and the ideal current command becomes smaller than a predetermined reference value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
