ABSTRACT:
Device and method for controlling supply of current and static capacitance to compressors, the device including a control signal providing part for providing control signals for controlling currents and static capacitances to be supplied to main windings and supplementary winding of the compressors, a current controlling part for limiting a current of the utility voltage supply in supplying the current to the main windings during starting in response to the control signals and releasing the limiting of the current in the supplying to the main windings after the starting, and a static capacitance controlling part for supplying respective starting static capacitances to the supplementary windings in a sequence in starting, and respective operative static capacitances to the supplementary windings in starting, and supplying only the respective operative static capacitances to the supplementary windings after the starting, in response to the control signals.
