摘要： 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.

摘要： A linear compressor operating apparatus includes a rectifying and filtering unit for converting an alternating current into a direct current, an inverter for inverting the direct current outputted from the rectifying and filtering unit into a desired frequency alternating current for operating a linear compressor in accordance with the alternating current outputted from the inverter, a position sensor for detecting a position of a piston of the linear compressor and outputting a position signal in accordance with said detection, a current detector for detecting the current running through the linear compressor, and a controller for receiving a current signal outputted from the current detector and a position signal outputted from the position sensor and outputting a pulse width modulating signal to control the inverter. The apparatus obtains a constant value of an interval which determines the efficiency of the linear compressor, regardless of a load thereof and optimizes a phase angle between the driving current and the compressor piston.
