Abstract
A control circuit of a power conversion apparatus is provided with a switch driving unit that drives the upper and lower arm switches; a short circuit control unit that causes the switch driving unit to execute a short circuit control when a failure occurs in the system, the short circuit control turning an ON side switch to an ON state and turning an OFF side switch to an OFF state; a checking unit that executes a checking process to check whether the short circuit control is able to perform correctly; and a protection control unit that causes the switch driving unit to execute a protection control when a failure occurs on either the upper arm switch or the lower arm switch, the protection control turning the switch where the failure occurs to an OFF state. The control circuit enables the protection control during execution of the checking process.
