Abstract
An output control apparatus for a linear compressor and a method of the same are disclosed. In the conventional art, when controlling an output of the linear compressor using a stroke, it is possible to implement a constant stroke. However, since the intermediate position of the piston is varied, it is impossible to constantly implement a top dead point. Therefore, an output control of the linear compressor is difficult, and a higher efficiency is not easily implemented. In addition, there is a problem for constantly controlling an output of the linear compressor. Therefore, in the present invention, the timing when the piston and discharge valve collide with each other is determined, and a certain degree of stroke is determined as a control reference stroke based on the thusly determined stroke for thereby controlling the stroke and driving a linear compressor, and then the linear compressor is driven by controlling the stroke, so that it is possible control an output having no deviation in accordance with the system, whereby a higher efficiency operation is implemented irrespective of the size of the load.
