Title:
AC ROTATING MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/098555
Kind Code:
A1
Abstract:
Provided is an AC rotating machine control device capable of on/off-controlling a non-failed set of switching elements in consideration of a state of an AC rotating machine concerning a failed set of windings. For a failed set of switching elements, the AC rotating machine control device stops a dq-axis current control and at least turns on the switching element of each phase on the same positive or negative side as a failed switching element in the case of a short-circuit failure, or turns off the switching element in the case of an open failure. For a non-failed set, the AC rotating machine control device continues the dq-axis current control and varies a d-axis current component in accordance with a state of the AC rotating machine concerning the failed set of windings.
