Original Abstract Submitted
a motor driving device includes a direct current (dc) link capacitor configured to store dc power, and an inverter configured to convert the dc power stored in the dc link capacitor into ac power and supply the ac power to a motor. the motor driving device includes a shunt resistor configured to sense current flowing through the inverter and detect whether the current has reached threshold current for controlling a regenerative voltage during a braking operation. a control unit is configured to control an operation of the inverter and perform a regenerative operation when the braking operation is started. the control unit, during the regenerative operation, switches motive power of a drum connected to the motor into regenerative energy and transmit the regenerative energy to the dc link capacitor, by controlling active component current and reactive component current together in response to the reaching of the threshold current.
