Dispositivo e método para controlar a alimentação de corrente e capacitância estática para um compressor

摘要

Device and method for controlling supply of current and static capacitance to a compressor, the device including a control signal generating part for providing a control signal for controlling a current and a static capacitance provided to the compressor different in starting and after the starting, a current controlling part for limiting a current of a utility voltage in supplying the current to a main winding in starting and releasing the limiting after the starting by changing an internal circuit in response to the control signal, and a static capacitance controlling part for supplying a starting static capacitance and an operative static capacitance from the current of the utility voltage to a supplementary winding in starting, and the operative static capacitance after the starting by the change of the internal circuit in response to the control signal.
