ELECTRIC MOTOR DRIVE DEVICE AND CONTROL METHOD

摘要

The present invention relates to an electric motor drive device, and a control method thereof, which supplies one electric motor with power from both a first inverter and a second inverter. A control unit that controls the output of the inverters first increases the output of the inverter on the side on which a drive control system initial diagnosis completes first. Further, when one inverter overheats, the control unit lowers the output of the overheated inverter and maintains or increases the output of the other, normal-temperature inverter.
