Abstract:
A device for controlling a supply of a current and a static capacitance to a compressor comprising:a control signal generating part for providing a control signal for controlling the current and the static capacitance provided to the compressor, such that the current and the static capacitance differ between a starting period of the compressor and after the starting period; a current controlling part for limiting a current of a utility voltage in supplying current to a main winding in the starting period, and for releasing the limiting of the current of the utility voltage after the starting period, by changing an internal circuit in response to the control signal; and, a static capacitance controlling part for supplying a starting static from the current of the utility voltage to a supplementary winding in the starting period, and for supplying an operative static capacitance after the starting period, by changing an internal circuit in response to the control signal.
