    摘要: An apparatus and method for determining the presence or absence in a motor lock error in a sensorless motor. The method includes the steps of: driving the sensorless motor; determining whether or not a predetermined time elapses after the sensorless motor has been driven; measuring a current applied to the sensorless motor after the lapse of the predetermined time; calculating a difference between the measured current with a predetermined reference current; and determining the presence or absence of a motor lock error in the sensorless motor by determining whether the determined difference is equal to or higher than a predetermined reference difference, so that it quickly determines the presence or absence of a motor lock error in the sensorless motor without using a sensor and prevents an overcurrent from flowing in the sensorless motor, resulting in the prevention of a faulty operation or damage to the sensorless motor.

    摘要: An improved method for detecting a laundry weight in a washing machine employing a sensorless BLDC motor is provided. The motor is rotated until the washer reaches a first speed. The washer then operates in a torque control mode for a predetermined amount of time, and a laundry weight is then determined based on a speed of the motor after the predetermined amount of time has elapsed. In this manner, laundry weight can be accurately determined and the laundry can be effectively washed. Additionally, since a washing machine employing this improved method for detecting does not require a hall sensor and its peripheral circuit manufacture is simplified, and thus cost may be reduced.

    摘要: Disclosed are a voltage compensating apparatus and method for a 3-phase inverter using four switches, to compensate for a severe distortion of a 3-phase application voltage due to a voltage ripple. The voltage compensating apparatus includes upper and lower DC link capacitors connected to each other in series and adapted to receive an input DC voltage, and to charge the DC voltage therein, a B4 inverter supplying a voltage to a 3-phase motor 1, using the four switches, when it receives the charged voltage from each of the DC link capacitors, a diodebridge receiving an AC voltage from an AC voltage source, rectifying the received AC voltage into a DC voltage, and applying the rectified DC voltage to the upper and lower DC link capacitors as the input DC voltage, and a triac coupled at an input terminal thereof to one line of the AC voltage source while being coupled at an output terminal thereof to a connection node between the upper and lower DC link capacitors, the triac serving to control whether or not the upper and lower DC link capacitors are to be charged with the DC voltage, respectively. In accordance with the present invention, the upper and lower DC link capacitors are charged through different paths, respectively. Accordingly, a control for DC link voltages is enabled to achieve a reduction in voltage ripple while minimizing a degradation in performance.
