Title:
Power converter and control method of power converter
Document Type and Number:
Japanese Patent JP6363944
Kind Code:
B2
Abstract:
The invention discloses a power transformation device and a control method for the same, which can accurately and fast determine whether the wheel is abnormal or whether other devices are abnormal even the vehicle is in a driving state. The power transformation device comprises an axle which is driven by the electromotor, a speed detection sensor which detects the rotation frequency of the axle, the current detection sensor which detects the current of the electromotor and a control device which controls the current of the electromotor based on the rotation frequency outputted by the speed detector; the control device has a rotation frequency monitor which monitors the rotation frequency inputted from the speed detection sensor and outputs the monitoring result when the rotation frequency satisfies the stipulated condition, and a fixed discriminator which performs comparison on the inputted detection value inputted from the current detection sensor and the preset target value when inputting the monitoring result from the rotation frequency monitor, and outputs the comparison result based on the comparison result.
