Abstract

An apparatus for controlling an operation of a linear compressor includes: a sensorless circuit unit for detecting a current and a voltage applied to a linear compressor and outputting a work operation value corresponding to them; a stroke controller for receiving the work operation value and outputting a switching control signal corresponding to a variation amount of the work operation value; and an electric circuit unit for receiving the switching control signal from the stroke controller and outputting a certain voltage to the linear compressor, accordingly, a TDC of the piston in consideration of an error due to the nonlinear characteristic can be controlled, and thus, an operation efficiency of the linear compressor can be improved.

Description

technical field [0001] The present invention relates to an apparatus and method for controlling the operation of a linear compressor, and more particularly, to an apparatus and method for controlling the operation of a linear compressor in which operational operating values ​​are obtained by using current and voltage, and The stroke is controlled according to the variation of the working operation value. Background technique [0002] Generally, a compressor is used to increase the pressure of coolant vapor (ie, compress the vapor) so that the coolant vapor evaporated from the evaporator can be easily condensed. [0003] According to the operation of the compressor, the coolant is repeatedly condensed and evaporated in the refrigeration equipment in order to transfer heat from a cool place to a warm place. [0004] Recently, various types of compressors are being used, among which a reciprocating compressor is the most commonly used one. [0005] R...
