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.

Abstract: A washing machine that minimizes noise of a motor while maintaining deceleration of the motor is provided. The washing machine includes a drum, a motor configured to rotate the drum, an inverter circuit configured to drive the motor, memory, comprising one or more storage media, storing instructions, and one or more processors communicatively coupled to the inverter circuit and the memory. The instructions, when executed by the one or more processors individually or collectively, cause the washing machine to control the inverter circuit based on a d-axis current command value and a q-axis current command value and control the inverter circuit to perform a soft brake for a preset time and control the inverter circuit to perform a short brake based on an elapse of the preset time, for decelerating the motor.
