Abstract:
A power conversion device, that includes a drive circuit  11 a  that drives a switching element  4  included in an upper-arm for one of three phases, a drive circuit  11 b  that drives a switching element  5  included in a lower-arm for the one phase, and a control circuit  9  that transmits a control signal to the drive circuits  11 a,  11 b , is provided. The power conversion device includes power supply circuits  12 a,  12 b  that provide power to the drive circuits  11 a,  11 b , respectively, a low-voltage power supply  6  that supplies power to one of the power supply circuits,  12 a , and a high-voltage power supply  1  that supplies power to the other of the power supply circuits,  12 b . Accordingly, it is possible to reliably protect a system: by realizing minimal redundancy of the power supply, the power supply generation circuit, etc.; and by realizing the short-circuit mode at the time of error occurrence.

Claim (Index 5):
The power conversion device according to  claim 4 ,\n wherein the second control circuit, to which the error detection signal from the first control circuit is input, in the case where an error in a voltage supplied to the low-voltage side power supply generation circuit is detected based on the error detection signal, generates the control signal that turns on the switching element of the corresponding arm according to the corresponding drive circuit via the first power supply circuit or the second power supply circuit having the high-voltage power supply as a power supply source.
