Abstract

A power conversion device is provided between a power supply and a load, and converts power from the power supply and supplies the converted power to the load. The power conversion device includes a plurality of switching elements composed of semiconductor elements, and a control device which generates drive signals for controlling the plurality of switching elements. Voltages are respectively applied to the plurality of semiconductor elements, on the basis of the drive signals generated by the control device. The plurality of semiconductor elements have equivalent failure probabilities due to neutron beams. Thus, a failure of the power conversion device due to neutron beams is prevented, and size increase thereof is suppressed.
