An electric-power conversion apparatus includes a driving circuit that performs switching control of semiconductor switching devices, a short-circuit control means that performs short-circuit control of an electric-power conversion circuit, an excessive-current detection means that detects whether or not an abnormality caused by an excessive current exists in the semiconductor switching device, and a gate-drive-abnormality detection means that detects whether or not an abnormality exists in a gate voltage of the semiconductor switching device; based on a result of the abnormality detection by the excessive-current detection means and a result of the abnormality detection by the gate-drive-abnormality detection means, the short-circuit control means turns on all the semiconductor switching devices in any one of the upper arm and the lower arm so as to perform the short-circuit control.
