Title:
INVERTER APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/047843
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, an inverter apparatus (100) comprises: a power converter (101) for an armature winding; a power converter (102) for a field winding; a velocity control unit (110) which controls three-phase current on dq-axes; a field current control unit (120) which controls field winding current; a simulator (130); and a damper winding failure detection device (200). The damper winding failure detection unit (200) has: a switching unit (210) which switches between a normal operation mode and a failure inspection mode; an inspection current command value generation unit (220) which outputs an AC as a q-axis current command and outputs a DC equivalent value as a d-axis current command in the failure inspection mode; and an inspection time measurement/determination unit (230) which measures a response in a field winding (13) and determines, from a response signal, the presence or absence of anomaly in the damper winding.
