Abstract:
To control an inverter in the event of an arm failure of a power converter, fluctuation in an output torque is suppressed, and reduction of a total output caused by the failure is suppressed by distributing an output into a plurality of inverters. A power converter for driving a redundant motor having a pair of first and second independent coils, includes: a first inverter circuit connected to the first coil; a second inverter circuit, independent from the first inverter circuit, connected to the second coil; and a first phase relay provided between the first inverter circuit and the first coil. When any one of a plurality of arms of the first inverter circuit fails, the first phase relay shuts off conduction between the failed arm and the first coil, and the redundant motor is driven by operating the second inverter circuit and the remaining arms of the first inverter circuit.

Claim (Index 10):
The power converter according to  claim 1 ,\n wherein the first inverter circuit outputs substantially zero at a predetermined rotation phase, wherein the second inverter circuit is operated such that an average output at the predetermined rotation phase is larger than an average output at phases other than the predetermined rotation phase, wherein the predetermined rotation phase is an electrical angle of 120\u00b0, wherein an output of the second inverter circuit is set such that a value obtained by integrating the output across a phase range of 360\u00b0 (electrical angle) is equal to or smaller than a value obtained by integrating a 100% output of the second inverter circuit across a phase range of 360\u00b0 (electrical angle), and a current value of the output does not exceed an upper limit of an allowable current of a switching element of the second inverter circuit, and the failure is a short-circuit failure.
