Abstract
A power conversion device is configured to convert power supplied from a power source into a driving current of a motor. A first semiconductor switching element of the power conversion device is disposed between a phase output of the power conversion device and the power source. A second semiconductor switching element of the power conversion device is disposed between the phase output of the power conversion device and a ground. The power conversion device further includes a first semiconductor switching element group.
