<p>A compressor unit and a refrigerator using the unit, the compressor unit comprising a compressor (3), an inverter (2) for driving the compressor (3), and an over-current protective device for protecting the inverter (2) against an output over-current, wherein a control part (6) controls the output voltage of the inverter (2) when the compressor (3) is started based on a ambient temperature detected by a temperature sensor (7) so that the input current of the inverter (2) does not exceed the working current value of the over-current protective device having temperature characteristics varying according to the ambient temperature, whereby a start torque can be increased by increasing the output voltage of the inverter without operating the over-current protective device when the compressor is started at a low temperature when a start load is increased.</p> |
