Abstract: A fault diagnosis method of a power electric system for a vehicle may include driving an inverter to output an output voltage command for fault detection; measuring a current input to each phase of a motor connected to the inverter; measuring a voltage of the neutral stage of the motor; and determining whether there are faults of a connection member connecting between the inverter and the motor and a relay connected to the neutral stage of the motor based on the measured current input to each phase of the motor and the voltage of the neutral stage.

Abstract: A charging system configured for reducing a leakage current may include an on board charger (OBC) receiving an alternating current (AC) power supplied from an external source to charge a vehicle battery with the AC power; at least an electric component connected to an output end portion of the OBC; at least a switch selectively connecting the electric component to or from a ground; and a controller connected to the at least a switch and reducing the leakage current flowing to the ground by controlling the switch connected to the electric component depending on whether or not the vehicle battery is charged with the AC power.

Abstract: An apparatus for controlling an inverter to drive a motor includes: a current control processor generating a voltage command for generating d/q axis current detection values, which are obtained by measuring current supplied to the motor, to follow a d/q axis current command for driving the motor, the current control processor converting the voltage command, which is sampled according to a sampling frequency generated based on a voltage vector phase of the voltage command, into a voltage vector corresponding to a point on each vertex and each side of a hexagon in a voltage vector diagram to apply a resulting value to the inverter driving the motor; and a sample frequency computing processor computing the sampling frequency based on the voltage vector phase of the voltage command and a reference number of sampling times during one rotation period of the motor.

Abstract: A method and a system for controlling a motor for a vehicle are provided. The vehicle is capable of being continuously driven by controlling the motor based on position information of a rotor derived using a sensorless estimation algorithm in the event of a failure of a position sensor of a motor rotor while the vehicle is being driven.
