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 11):
A power conversion device comprising:\n a first drive circuit that drives a switching element of one an upper-arm and a lower-arm for one of three phases; a second drive circuit that drives a switching element of the other of the upper-arm and the lower-arm; a first control circuit that generates a control signal for the first drive circuit; and a second control circuit that generates a control signal for the second drive circuit, wherein the power conversion device includes a first power supply generation circuit and a second power supply generation circuit that have a common power supply source, and power is supplied to the first control circuit by the first power supply generation circuit and power is supplied to the second control circuit by the second power supply generation circuit.
