ABSTRACT:
An apparatus and method for controlling a linear compressor is provided. The linear compressor controlling apparatus includes a voltage detection unit, a current detection unit, a control unit and a compressor drive unit. The voltage detection unit detects a voltage supplied to the linear compressor, while the current detection unit detects a current supplied to the linear compressor. The control unit determines whether a collision of a piston of the compressor with a valve of the compressor occurs using output signals of the voltage and current detection units, and controls the amplitude of the piston if the collision of the piston with the valve occurs. The compressor drive unit controls the amplitude of the piston under the control of the control unit.
