Title:
POWER CONVERSION DEVICE, MOTOR MODULE, AND ELECTRIC POWER STEERING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/069919
Kind Code:
A1
Abstract:
This power conversion device converts power supplied from a power source to power to be supplied to a motor having n-phase (n is an integer of 3 or greater) winding. The power conversion device is provided with a first inverter that is connected to one end of the winding of each phase of the motor, and a second inverter that is connected to the other end of the winding of each phase of the motor. The power conversion device has a first driving mode of performing n-phase energization control using motor neutral points formed in one of the first and second inverters and the other inverter, and a second driving mode of performing n-1-phase energization control using both the first and second inverters. In abnormal control, switching between the first driving mode and the second driving mode is performed.
