  "textContent": "In discharging of electric power in a smoothing capacitor arranged between a battery and an inverter provided with three-phase power modules, a control circuit alternately and periodically switches between all-phase upper on control and all-phase lower on control. With a power module in which a current flows in a direction from a motor toward the inverter among the three-phase power modules being defined as a negative current module and a power module in which a current flows in a direction from the inverter toward the motor being defined as a positive current module, during a period during which switching between all-phase lower on control and all-phase upper on control is made, the control circuit performs, for a prescribed time period, discharging processing for setting the negative current module to the lower on state and for setting the positive current module to the upper on state.",
