Device and method for controlling supply of current and static capacitance to compressor

Abstract

Device and method for controlling supply of current and static capacitance to a compressor, the device including a control signal generating part for providing control signals for controlling a current and a static capacitance to a main winding and a supplementary winding of the compressor, a current controlling part for limiting the current of the utility voltage to the main winding in the starting and supplying the current to the main winding regularly after the starting 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 starting, and for supplying only the operative static capacitance after the starting, in response to the control signal.
