Similarly, when converter 5b2 self-detects a failure, contactor 11a is turned off and contactor 11b is turned on. Thereby, the battery 8a supplies electric power only to the tertiary circuit C3 via the DC / DC converter 9.
- the AC electric vehicle 1E when the AC electric vehicle 1E detects a failure of the converter 5b2, the AC electric vehicle 1E automatically operates the contactors 11a and 11b so that the power supply destination of the battery 8a is only the tertiary circuit C3.
- the power supply by the battery 8b is added, whereby the power supply to the tertiary circuit C3 can be strengthened.
- the state in which the contactors 11a and 11b are automatically operated is not limited to the pattern shown in each embodiment. Whether or not the contactors 11a and 11b are automatically turned on or off can be appropriately determined depending on the environment in which the AC electric vehicle is applied, the driving situation, or the like.
- the contactors 11a and 11b are turned on by the regeneration command signal output from the vehicle control device 13, but the present invention is not limited to this.
- the inverter 6a that has received the regeneration command signal output from the vehicle control device 13 may output a signal for turning on the contactors 11a and 11b.
- the converter 5b1 is configured to self-detect a failure and operate the contactors 11a and 11b, but is not limited thereto.
- the vehicle control device 13 may detect the failure of the converter 5b1 and operate the contactors 11a and 11b. Further, the contents detected for operating the contactors 11a and 11b are not limited to the failure of the converter 5b1. Others may be used as long as the power supplied to the tertiary circuit C3 is assumed to be unstable.
- any method may be used for detecting a failure of the converters 5b1 and 5b2.
- a DC voltage monitoring device 15b may be provided to self-detect a failure.
