摘要: An inverter control apparatus for controlling a command frequency (f1) and a command voltage (V1) to be supplied to an inverter (2) which then supplies AC power of a desired frequency determined by the command frequency and the command voltage to an induction motor (1). The inverter control apparatus receives a requested rotational speed (fref) of the motor and an actual rotational speed (f') obtained by detecting a frequency of a fluctuation component of a drive current supplied from the inverter (2) to the induction motor (1). A difference between the requested rotational speed and the actual rotational speed represents a slip amount, which is added to the requested rotational speed to produce a command frequency. The command voltage is set to a voltage when the monitored drive current is at a minimum value.
