A control device for an AC electric vehicle that is applied to a configuration in which an SIV 7 is connected to an intermediate DC circuit unit 40 between a CONV 3 that converts an AC voltage input through a main transformer 2 to a DC voltage and an INV 4 that converts the DC voltage to an AC voltage, in which a carrier frequency fc of the CONV 3 is changed on the basis of initial temperature (initial value of Tcnv) of a converter main circuit element when a vehicle is stopped and input current Isiv of the SIV 7 such that a temperature variation of a converter main circuit element when the vehicle is stopped is reduced.
