A hermetic compressor driving device, which drives a hermetic compressor (20) provided with an HPS (High Pressure Switch) (24) therein, includes parameter detection units (a voltage detection unit (12), an overcurrent detection unit (13), and a position and open-phase detection unit (16)) that detect an overcurrent, a bus voltage, and an open phase, which are generated during the opening operation of the HPS (24) within the hermetic compressor (20); a temperature detection unit (17) that detects the temperature of the hermetic compressor (20); and a control unit (14) to which data acquired by the parameter detection units and the temperature detection unit (17) is input. When detecting an abnormality on the basis of the data and upon determining the abnormality as a resumable abnormality, the control unit (14) outputs a drive signal; and, upon determining the abnormality as being not a resumable abnormality, outputs an abnormality signal. |
