57AbstractABA power converter having: a drive circuit 11a for driving a switching element 4 constituting the upper arm of one phase portion, a drive circuit 11b for driving a switching element 5 constituting the lower arm of the one phase portion, and a control circuit 9 for transmitting a control signal to the drive circuits 11a, 11b, wherein the power converter is provided with: power supply circuits 12a, 12b for supplying power to the drive circuits 11a, 11b, respectively; a low-voltage power supply 6 for supplying power to one power supply circuit 12a; and a high-voltage power supply 1 for supplying power to the other power supply circuit 12b. A system is thereby reliably protected in which a short-circuit mode is realized when an abnormality occurs, while the power supplies and power supply generation circuits are made as minimally redundant as possible.
