Abstract: A washing machine including a motor regenerative braking configuration uses a buck power converter capable of reducing a direct current (DC) voltage, in association with charging an energy storage device when a voltage of a DC link capacitor becomes greater than or equal to a certain voltage. The washing machine uses the buck power converter in association with discharging the energy storage device and charging the DC link capacitor when the voltage of the DC link capacitor decreases. The washing machine may utilize regenerative braking energy by reducing or increasing a voltage amount provided from the energy storage device to a load by using a power conversion device.
