Abstract:
1. A driving controlling apparatus for a reciprocating compressor, comprising: an output capacity determining unit for determining an output capacity of the reciprocating compressor; an over-stroke preventing unit for preventing an over-stroke of a motor inside the reciprocating compressor; an impedance matching unit for matching an inductance of the motor of the reciprocating compressor to an impedance of the apparatus; and a power switching device installed between the motor and a power source, for cutting off power supplied to the motor of the reciprocating compressor, wherein the over-stroke preventing unit comprises: a Positive Temperature Coefficient device for generating heat according to a current amount; and a switching device serially connected to the Positive Temperature Coefficient device, for cutting-off a current flowing to the Positive Temperature Coefficient device, and wherein the impedance matching unit comprises: two capacitors connected to each other in parallel; and switching devices respectively connected to the two capacitors.
