Title:
AC MOTOR CONTROL DEVICE, ELECTRIC VEHICLE, AND AC MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/053181
Kind Code:
A1
Abstract:
Provided is an AC motor control device that drives and controls an AC motor through voltage phase control, and is capable of speeding up the overall response while suppressing reverse current response. The AC motor control device converts DC power to AC power on the basis of a voltage phase command output from a voltage phase control unit and outputs the AC power to an AC motor. The AC motor control device is characterized in that the voltage phase control unit includes a change amount limiting unit that limits the amount of change in the voltage phase.
