Abstract
Driving controlling apparatus and method for a reciprocating compressor capable of stably driving a reciprocating compressor when a reciprocating compressor is operated or an output capacity of the reciprocating compressor is varied, by matching an impedance of the apparatus to an inductance of a motor, and capable of enhancing an efficiency of the reciprocating compressor. The apparatus comprises an output capacity determining unit for determining an output capacity of a reciprocating compressor; an over-stroke preventing unit for preventing an over-stroke of a motor inside the reciprocating compressor; and an impedance matching unit for matching an inductance of the reciprocating compressor to an impedance of the apparatus.
