Abstract
A power conversion device includes a plurality of converter cells, and the converter cellincludes: an upper arm, which includes a semiconductor switching elementconfigured to allow conduction in only one direction and a diodeconnected in anti-parallel to the semiconductor switching element; and a lower arm, which is connected to the upper arm, and includes a semiconductor switching elementconfigured to allow reverse conduction and a diodeconnected in anti-parallel to the semiconductor switching element, in which the semiconductor switching elementand the diodeof the lower armare simultaneously set to conductive states to split an electric current to flow through the diodeto the semiconductor switching element
