Output control apparatus for linear compressor and method of the same

An output control method for a linear compressor, comprising:

• a first step for storing a stroke outputted from a stroke computation unit;
• a second step for judging whether a collision has occurred between a piston installed in a compressor and a discharge valve;
• a third step for resetting a control destination stroke based on the stroke stored in the first step when a collision is detected in the second step and controlling an output of the linear compressor based on the newly set control destination stroke;
• and
• a fourth step for obtaining the control setting stroke stored in the first step when a collision is not detected in the second step.

An output control method for a linear compressor, comprising:

• a first step for computing an operating stroke based on a voltage and current inputted;
• a second step for storing a maximum current value for a predetermined time set by a user when driving the linear compressor;
• a third step for comparing the stored maximum current value with a reference current value corresponding to a collision;
• a fourth step for calculating a new control destination stroke based on the current stroke when the maximum current value is greater than the reference current value in the third step and controlling an output of the linear compressor based on the set control destination stroke;
• and
• a fifth step for controlling an output of the linear compressor based on the previously set control destination stroke when the maximum current value is smaller than the reference current value in the third step.
