Abstract

A power conversion device includes a first switching element configured by using a first semiconductor material and a second switching element connected in parallel with the first switching element and configured by using a second semiconductor material having a band gap narrower than that of the first semiconductor material. The power conversion device further includes a control device configured to selectively execute any one of first switching control and second switching control of intermittently turning on the first switching element and the second switching element, respectively, according to a current command value. A size of the first switching element is smaller than a size of the second switching element. The control device selects the first switching control if the current command value is smaller than a first threshold value and selects the second switching control if the current command value is larger than a second threshold value.
