An electric power system of the vehicle includes: first power lines which are connected to a high-voltage battery; second power lines, which are connected to a direct-current input-output side of a first inverter; a second smoothing condenser, which is arranged on the second power lines; a low-voltage DCDC converter, which is connected in parallel with the high-voltage DCDC converter to the first power lines; and a drive circuit, which drives a switching element of the low-voltage DCDC converter; the second power lines and the drive circuit are connected by a third power line, and on the third power line, a voltage-reducing device, which reduces a voltage of electric power from the second smoothing condenser and supplies the electric power to the drive circuit to consume the electric power by the drive circuit.
