Document Type and Number:
WIPO Patent Application WO/2019/207752
Kind Code:
A1
Abstract:
Provided is a rotating machine power conversion device achieving operation continuation in an operation continuable rotational speed region even if an off-failure occurs in one phase of a power conversion means constituted by switching elements. The rotating machine power conversion device is provided with: a normal/abnormal time current control unit selection unit (12) for switching between a normal time current control unit (9) and an abnormal time current control unit (10) according to the determination result of an abnormality determination means (7); and an abnormal time current control unit/power conversion stop unit selection unit (13) for switching between the abnormal time current control unit (10), which is used by a rotational speed calculation means (6) when rotational speed is smaller than a predetermined rotational speed, and a power conversion stop unit (11), which is used when the rotational speed is larger than the predetermined rotational speed.
