A drive system includes a first switching unit, a first capacitor, a step-down circuit, a second capacitor, and a discharging unit. The first switching unit is configured to convert energy, stored in an electrical storage device, to electric power that is supplied to a motor. The first capacitor is connected to the first switching unit and configured to smooth voltage that is supplied from the electrical storage device to the first switching unit. The step-down circuit is connected to the first capacitor and configured to step down voltage of the first capacitor. The second capacitor is connected to the step-down circuit and configured to draw electric charge stored in the first capacitor. The discharging unit is configured to discharge electric charge stored in the second capacitor. |
