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 19):
The power conversion device according to  claim 11 ,\n wherein the power conversion device is enabled to perform: a short-circuiting operation of load by turning on the switching element of the upper-arm or the lower-arm when a direct current bus bar voltage, that is a voltage between the two ends of a serial circuit of the upper-arm and the lower-arm, arrives at a first threshold value; an operation of releasing the short-circuiting operation when the direct current bus bar voltage arrives at a second threshold value that is less than the first threshold value; and a discharge operation of causing a smoothing capacitor, that is connected in parallel with the serial circuit, to discharge, and wherein, when the direct current bus bar voltage arrives at the second threshold according to the short-circuiting operation, the discharge operation is stopped and the stopped state is maintained.
