Title:
DRIVE-DEVICE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/043234
Kind Code:
A1
Abstract:
A technique that, without increasing the scale of a control device that controls a drive device provided with a variable-magnetic-flux dynamo-electric machine, can keep the induced voltage within the voltage tolerance of an inverter. This drive-device control device controls a drive device provided with: a dynamo-electric machine that has a rotor, provided with a permanent magnet, and a stator, provided with a coil; a magnetic-field adjustment mechanism that changes the magnetic flux; and an inverter. When disconnection conditions under which the drive device is to be disconnected from a DC main power supply become satisfied, if it is determined that the drive device is in an overvoltage state in which the induced voltage induced in the coil by the rotation of the rotor is greater than the voltage tolerance of the inverter, the control device: maintains the connection to the main power supply regardless of the disconnection conditions, at least until the overvoltage state ends; controls the dynamo-electric machine using weaker-magnetic-field control in which a weaker-magnetic-field current that weakens the magnetic flux is supplied to the coil; and disconnects the main power supply in accordance with the disconnection conditions after the overvoltage state ends.
