Study on the performance and control of linear compressor for household refrigerators

Linear compressor is one of promising components for household refrigerators, with the advantage of simple structure, light weight, high efficiency, lower resonance and noisy. In this paper, the researching status and developing trend of linear compressor are presented. The structure, the operation principle and the characteristics of the moving-coil, moving-magnet, and moving-iron type linear compressor are analyzed in details. The features of linear switched reluctance actuator are investigated, and it is recommended to be a competitive candidate for linear compressor in household refrigerators.
