摘要： An air conditioning apparatus using a refrigerating cycle in which a scroll compressor is used to compress a refrigerant. The scroll compressor is driven by an induction motor. The speed of the induction motor is controlled by a PWM type inverter which produces an AC voltage of variable frequency. A carrier frequency higher than 10 KHz is used to effect pulse width modulation of the AC voltage of the inverter, whereby generation of uncomfortable noise is avoided. A control unit is provided to detect slip of the induction motor and to adjust the detached slip to a predetermined optimum value, thereby avoiding excessive lowering of the speed of the motor which may cause lack of lubricating oil for the compressor.

摘要： Inverter control method and apparatus which are immune to the influence of load disturbance and detection noise and permit stable minimization control of motor current, in order to attain high efficiency of an AC motor and of an inverter adapted to drive the same. A memory group is provided having a plurality of sets of memories for storage of data pieces representative of exciting current commands standing for manipulated variables and data pieces representative of motor currents standing for controlled variables. An upper limit value (IDUP) and a lower limit value (IDLW) defining a fluctuation region of the exciting current command are determined so that an exciting current command data piece corresponding to a motor current data piece which is the smallest of all the current data pieces in the memory group falls within the fluctuation region. The fluctuation region is determined so as to minimize the motor current, the exciting current command being fluctuated within the fluctuation region.
