Abstract

A control apparatus for a power conversion system is a control apparatus for a power conversion system including a power converter connected to a power supply or a capacitor through a wire, a coil disposed at a position around the wire where a magnetic flux is linked with the coil when a short-circuit failure in which a voltage of the power supply or the capacitor is short-circuited occurs, the magnetic flux being generated by the short-circuit failure, and a voltage detection circuit configured to detect a voltage value of a voltage across the coil. The control apparatus includes: a voltage acquisition unit configured to acquire the voltage value of the voltage across the coil detected by the voltage detection circuit; and a failure detection unit configured to detect a short-circuit failure of the power converter, based on the voltage value acquired by the voltage acquisition unit.
