CONTROL DEVICE FOR ELECTRIC VEHICLE
DRIVE
July 21, 2022
A control device for an electric vehicle, includes: a DC power supply; a three-phase AC motor; an inverter that converts DC power supplied from the DC power supply into AC power and outputs the AC power to the three-phase AC motor; and a control unit that controls the inverter to control an input voltage to the three-phase AC motor. Further, when a parameter correlated with the input voltage includes a predetermined high frequency component, the control unit performs correction of adding a component for canceling out the high frequency component to the input voltage, and controls the three-phase AC motor based on the corrected input voltage.
