Abstract
A power conversion device includes a self-commutated power converter that performs power conversion between an AC circuit and a DC circuit, and a control device that controls switching operation of a switching element included in the self-commutated power converter. The control device performs first control to increase a switching frequency of the switching element when a control command value for the self-commutated power converter becomes equal to or greater than a first threshold value.
