A control circuit for a power converter that configures a system that is mounted to a vehicle and includes a rotating electric machine that has multiple phases and includes a rotor that is capable of transmitting power to and from a drive wheel, and the power converter that includes upper- and lower-arm switches that are electrically connected to phase windings of the rotating electric machine. The control circuit determines whether an abnormality has occurred in the system, determines whether the system has been started based on an output voltage of the insulating power supply, and performs short-circuit control to turn on an on-side switch that is either one of the upper- and lower-arm switches and to turn off an off-side switch that is the other of the upper- and lower-arm switches, in response to the system being determined to have been started, and the abnormality being determined to have occurred.
