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 2):
The power conversion device according to  claim 1 , further comprising:\n an error detection unit that detects an error of a power supply voltage of the first drive circuit or the second drive circuit, and outputs an error detection signal; and an error signal transmission circuit that transmits the error detection signal to the first control circuit, wherein the first control circuit transmits the control signal generated according to an error cause based on the error detection signal to the first drive circuit or the second drive circuit via a control signal transmission circuit, and turns on the switching element included in the upper-arm or the lower-arm.
