Claim 0:
1. A control device for a power conversion device using a multi-phase magnetic coupling reactor,
the multi-phase magnetic coupling reactor including:
a first outer coil;
a second outer coil;
an inner coil disposed between the first outer coil and the second outer coil; and
a core including a first outer core portion around which the first outer coil is wound, a second outer core portion around which the second outer coil is wound, and an inner core portion around which the inner coil is wound, wherein:
the first outer core portion, the second outer core portion, and the inner core portion extends in a first direction and are disposed side by side in a second direction orthogonal to the first direction;
the first outer core portion, the second outer core portion, and the inner core portion are connected by a first connecting portion that extends in a second direction on one end side in the first direction;
the first outer core portion, the second outer core portion, and the inner core portion are connected by a second connecting portion that extends in the second direction on the other end side in the first direction; and
directions of magnetic fluxes generated in the first outer coil, the second outer coil, and the inner coil are opposite to each other in any combination;
the control device is configured to switch among:
a one-phase operation of causing currents to flow through any one of the first outer coil, the second outer coil, and the inner coil to be operated;
a two-phase operation of causing the currents to flow through any two of the first outer coil, the second outer coil, and the inner coil to be operated; and
a three-phase operation of causing the currents to flow through all of the first outer coil, the second outer coil, and the inner coil to be operated;

the control device is configured to select two phases of the first outer coil and the second outer coil in the two-phase operation; and
the control device is configured to select one of the first outer coil and the second outer coil in the one-phase operation before the two-phase operation or a one-phase operation after the two-phase operation.
