<P>PROBLEM TO BE SOLVED: To provide an inverter device capable of preventing induction of harmonics components of a return current, by preventing vibration of a magnetic flux component current Id, even in a pulse region. <P>SOLUTION: A magnetic flux component current command corrector 7 for inputting a magnetic flux component current command Idp and a magnetic flux component current Id and outputting a magnetic flux component current correction value Idp2 is used, and the difference between the magnetic flux component current command Idp and the magnetic flux component current Id, which are the input of a torque controller 5, is used as the difference between the magnetic flux component current correction command Idp2 and the magnetic flux component current Id. In this way, induction of the vibration of the magnetic flux component current Id is suppressed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
