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 3):
The power conversion device according to  claim 1 ,\n wherein power is supplied from both the high-voltage power supply and the low-voltage power supply, and wherein the power conversion device further comprises a second control circuit that generates a control signal for the first drive circuit or the second drive circuit when an error occurs, and transmits the generated control signal to the first drive circuit or the second drive circuit via the control signal transmission circuit.
