A first offset correction and a second offset correction are switched between in a cycle Tc shorter than an electrical angle cycle of an alternating current rotating machine, the first offset correction is such that a first shift amount is fixed in such a way as to obtain an applied voltage such that at least n−2 phases among phase currents of the alternating current rotating machine can be detected, and the applied voltage is calculated by the first shift amount being subtracted equally from all voltage commands, and the second offset correction is such that a second shift amount is fixed in such a way that a sign of an average value in an electrical angle cycle is reversed with respect to that of an average value in an electrical angle cycle of the first shift amount, and the applied voltage is calculated by the second shift amount being subtracted equally from all the voltage commands.
