Abstract
A control device for a switched reluctance motor includes an inverter having a switching circuit that switches a magnetic pole to provide a first winding pattern or a second winding pattern. With respect to a boundary dividing a driving range of the switched reluctance motor into two ranges, the control device performs switching to the first winding pattern when the torque and the rotational speed are located in the first range on the low load side, performs switching to the second winding pattern when the torque and the rotational speed are located in the second range, allows switching of the magnetic pole in a case where a current of the phase whose magnetic pole is to be switched among the three-phase coils is 0, and prohibits switching of the magnetic pole in a case where the current of the phase whose magnetic pole is to be switched is not 0.
