Title:
DRIVE CONTROL DEVICE FOR RAILWAY VEHICLES
Document Type and Number:
WIPO Patent Application WO/2014/112127
Kind Code:
A1
Abstract:
A drive control device for railway vehicles, that drive-controls a permanent magnet synchronizing electric motor driven by a three-phase alternating current. A power conversion unit converts, into a three-phase alternating current, power supplied from an external power supply via a feeder line and supplies same to the permanent magnet synchronizing electric motor via a U-phase AC current line, a V-phase AC current line, and a W-phase AC current line. A short-circuit contact unit is provided between the power conversion unit and the permanent magnet synchronizing electric motor, and causes a shorted state in which the U-phase AC current line, the V-phase AC current line, and the W-phase AC current line are mutually shorted.
