Title:
ELECTRIC POWER CONVERTER CONTROL DEVICE AND ELECTRIC POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/084566
Kind Code:
A1
Abstract:
Provided is an electric power converter control device for controlling an electric power converter which executes electric power conversion between a DC power supply and a motor, the electric power converter control device comprising a magnetic flux command value generation unit which obtains a magnetic flux command value on the basis of a torque command value and a rotation detection value indicating the number of rotations of the motor, a DC voltage value generation unit which obtains a DC voltage value indicating an output voltage of the DC power supply on the basis of at least a modulation factor coefficient serving as a target of the electric power converter and the magnetic flux command value, and a current command value generation unit which obtains a current command value for controlling the motor on the basis of the torque command value, the rotation detection value, and the DC voltage value.
