POWER CONVERSION DEVICE FOR ELECTRIC VEHICLE

To include a power converter 2 that drives an induction machine 1 and a control unit 5 that controls the power converter 2. The control unit 5 includes a drive stopping unit 10. The drive stopping unit 10 includes a secondary-resistance-temperature detecting unit 30 that detects temperature rise of a secondary resistance of the induction machine 1 based on a current (a d-axis-current detection value Id and a q-axis-current detection value Iq, or a d-axis current command Id* and a q-axis current command Iq*) detected by the induction machine 1, an inverter angular frequency Éinv calculated based on the current, and speed information Étrain of an electric vehicle detected by an external-speed-information detecting unit 14, and the drive stopping unit 10 also includes a drive-stopping-signal output unit 31 that outputs a drive stopping signal Gstop for stopping a driving operation of the power converter 2 based on the speed information Étrain of an electric vehicle and an output (deviation) from the secondary-resistance-temperature detecting unit 30.
