<P>PROBLEM TO BE SOLVED: To provide a power converter capable of easily removing a harmonics component whose frequency is lower than the carrier frequency contained in an output voltage of a power conversion circuit. <P>SOLUTION: One or more distributed calculation means DO1 to DOm-1 that perform calculation each time two or more carrier signals occur, among m kinds of distributed calculation means DO1 to DOm, are provided with interpolation calculation means CO1 to COm-1. The interpolation calculation means CO1 to COm-1 perform calculation for outputting to interpolate a current calculation result acquired from a current calculation, each time a carrier signal occurs during the period between a current calculation operation and a next calculation operation. The outputs of the interpolation calculation means CO1 to COm-1 are added to the output of the distributed calculation means DOm to generate a control command signal. <P>COPYRIGHT: (C)2004,JPO |
