PURPOSE: The upregulation of the voltage provided to compressor or the electricity facilitates. For voltage or the electricity, voltage and the stable power supply possibles in the shortage one phase sulfur. CONSTITUTION: A control device of compressor comprises a rectifier(40), a inverter units(10, 12), a first connector, a third connection part and a controllers(30, 32). It is input the AC power source and rectifier outputs to the direct current voltage. It is applied the direct current voltage and it changes according to the control signal into the AC voltage and the inverter unit sanctions in motor units(20, 22). The inverter unit comprises the first and the third electrical path of the first and the serially connected second switch device being included respectively and being parallely connected. The first and the third connection part respectively electrically interlink the first and the third connection point and connection tab. According to controller is the load, the first on the first and the third electrical path and the second switch is controlled respectively. Controller controls the inverter unit so that the AC voltage be applied in part of coil of the coil whole of the motor unit or the motor unit.
