  "textContent": "A power supply system () includes: a drive motor (M) coupled to drive wheels (W); a first inverter () which converts DC electric power into three-phase AC electric power; a first current sensor (I) which generates a current detection signal according to electrical current flowing in the first inverter (), and a system ECU () which executes discharge control for discharging electrical charge of a second smoothing capacitor (C) connected to the first inverter (), in a case of a discharge start condition being established. The system ECU (), in a case of the drive motor (M) rotating upon starting the discharge control, executes the discharge control, after executing three-phase short-circuit control to turn ON all switching elements of an upper arm or all switching elements of a lower arm of the three-phase arm of the first inverter (), based on the current detection signal of the sensor (I).",
