Title:
DEVICE AND METHOD FOR CONTROLLING SUPPLY OF CURRENT AND STATIC CAPACITANCE TO COMPRESSOR
Document Type and Number:
WIPO Patent Application WO2001035520
Kind Code:
A8
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 varied with a state of the utility voltage supply, and different before and after the starting, a current controlling part for limiting a current of the utility voltage supply in supplying the current to the main windings in common during starting in response to the control signals and releasing the limiting of the current in the supplying to the main windings in common after the starting, and a static capacitance controlling part for supplying respective starting static capacitances from the current of the utility voltage supply to the supplementary windings in a sequence in starting, and respective operative static capacitances from the current of the utility voltage supply to the supplementary windings on the same time in starting, and supplying only the respective operative static capacitances from the current of the utility voltage supply to the supplementary windings on the same time after the starting, in reponse to the control signals.
