Abstract
Provided is a power conversion device that can be realized with a small circuit and is capable of stably converting AC power inputted from a three-phase power source system into DC power. In a power conversion device: an output terminal of a common converter cell in a J-numbered stage is connected, together with output terminals of common converter cells of the other two phases, to common lines; an output terminal of an independent converter cell in a K-numbered stage is connected to independent lines independently of converter cells of the other two phases; and a plurality of switches comprise a common switch for switching the connection relationship between the common lines and DC buses, and an independent switch for switching the connection relationship between the independent lines and DC buses.
