| description | An apparatus for controlling an operation of a reciprocating compressor, includes: a control unit for detecting a current pushed amount of a piston when a TDC is detected as an inflection point of a phase difference between stroke and current, comparing the current pushed amount with a pushed amount reference value, and applying a DC voltage applied to a linear motor based on the comparison result. An AC voltage and a DC voltage are applied to the linear motor to increase the stroke, and when the TDC is detected, the current pushed amount is calculated and compared with the pushed amount reference value, and then, the DC voltage or a DC current applied to the linear motor is varied based on the comparison result, thereby obtaining a maximum compression volume without collision of the piston. |
