Abstract:
A device for controlling supply of current and static capacitance to a compressor comprising:a control signal generating part for providing control signals for controlling a current and a static capacitance of a utility voltage to be provided to a main winding and supplementary winding of the compressor, the current and static capacitance being different in starting of the compressor and after the starting of the compressor; a current controlling part for limiting the current of the utility voltage to the main winding in the starting of the compressor and supplying the current to the main winding regularly after the starting of the compressor in response to the control signal; and a static capacitance controlling part for supplying both a starting static capacitance and an operative static capacitance to a supplementary winding in the starting of the compressor, and for supplying only the operative static capacitance after the starting of the compressor, in response to the control signal.
