Abstract
A three-phase AC reactor according to an embodiment includes a peripheral iron core that forms an outer periphery, and at least three iron core coils that are in contact with or connected to inner surfaces of the peripheral iron core. Each iron core coil includes an iron core and a coil wound around the iron core. The at least three iron core coils form gaps between the iron core coils adjoining each other so as to be magnetically connectable through the gaps. Each coil has coil extension members that extend from coil ends to connection points to an external device.
