Abstract
In recent the energy efficiency of a refrigerator has been restricted extremely. A compressor consumes a great portion of input power in a refrigerator. So it is necessary to develop a more efficient compressor in these days. The existing reciprocating compressor need to a crank shaft to convert the rotating motion to the straight motion and is not efficient. But the linear compressor using mechanic resonance is efficient but need a drive instead of a crank shaft to control a position accurately. However it is impossible to apply a stroke sensor practically because of the internal circumstance of compressor. In this paper, A new sensorless stroke control method using the current and voltage of linear compressor is proposed.
