Abstract: PROBLEM TO BE SOLVED: To provide an induction motor control device, etc. which is adapted to realize more stable startup than ever or exert control to run an induction motor stably even when external disturbance is applied to it during operation.SOLUTION: MERSs 100u, 100v and 100w generate voltage equivalent to voltage generated by an AC power supply VS whose phase is varied by a value θset and apply voltage equivalent to a sum of this voltage and the voltage generated by the AC power supply to an induction motor M. A control unit 200 determines θset in such a way that a load current detected by a current detection unit GM converges to a value Iset and the effective value of a fundamental wave component of a load voltage detected by a voltage detection unit VM converges to a value Vset which is determined based on a deviation in the load current from the value Iset. While so doing, it also exerts feed-forward control so that a value proportional to the differential of this fundamental wave component and a value proportional to the load current become a value of θset, and then determines the transition timing of each gate signal based on this value of θset before feeding the gate signal to each MERS.
