Title:
POWER CONVERSION DEVICE, MOTOR DRIVE UNIT, AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/180274
Kind Code:
A1
Abstract:
The power conversion device converts power from a power source into power to be supplied to a motor having n-phase (n is an integer equal to or greater than 3) windings. The power conversion device is provided with a first inverter connected to one end of each phase winding of the motor and a second inverter connected to the other end of the each phase winding. The power conversion device is provided with a neutral point potential setting circuit which is connected to the first inverter and which sets a potential of a neutral point formed in the first inverter in the event of an abnormality in the first inverter.
